What is the chemical formula of the ionic compound ammonium phosphate?

(NH3)3PO4 Ammonium is a polyatomic ion with 1+ charge, and phosphate is a polyatomic ion with 3− charge. Putting these ions together gives the formula (NH4)3PO4, which is named ammonium phosphate.

Ammonium nitride is formed from the NH+4 cation and the N3− anion. What is the correct formula for this compound?

(NH4)3N An ionic compound must be electrically neutral, so it must have the same number of positive and negative charges. Three ammonium ions, each with a charge of 1+, would give us three positive charges, while one nitride ion, with a charge of 3−, would give us three negative charges. Therefore, the formula is three ammonium ions to one nitride ion: (NH4)3N.

Which of the following are true about electronegativity?

-Electronegativity generally increases as you move across the groups in a period (from left to right) on the periodic table. -Electronegativity is a measure of the tendency of a bonded atom to attract electrons towards itself -Atoms with higher electronegativity have a stonger attraction to the electrons in their bonds.

Which of the following will participate in dipole-dipole interactions? C2H6 CO2 H2O H2

-H2O Dipole-dipole attraction is the electrostatic force between the partially positive end of one polar molecule and the partially negative end of another, and water is the only polar molecule of these choices.

ICl is a polar molecule and Br2 is a non-polar molecule. Which molecule will have a higher boiling point?

-ICl ICl and Br2 have similar masses (∼160 amu) and the same shape (they are both linear molecules). Therefore, these molecules experience similar London dispersion forces. However, ICl is polar and thus also exhibits dipole-dipole attractions, while Br2 is nonpolar and does not. The relatively strong dipole-dipole attractions require more energy to overcome than London dispersion forces, so ICl will have the higher boiling point.

Which of the following is a step in creating a Lewis structure?

-Place all remaining electrons on the central atom. -Draw a skeleton structure of the molecule around the central atom. -Rearrange electrons of the outer atoms to make multiple bonds with the central atom.

-The two pans will have the same specific heat capacity. -The heat capacity of the larger pan will be greater than the heat capacity of the smaller pan.

What is being illustrated by the dotted lines in the following image?

-This illustrates the electrostatic attraction between the partially positive end of one polar molecule and the partially negative end of another. Dipole-dipole attraction occurs between partially positive ends of one polar molecule and partially negative ends of another. They are a form of electrostatic attraction like ion-ion attraction, but generally much weaker than those found in ions. Dipole-dipole interactions can be instantaneously attractive or repulsive depending on the orientations of the dipoles, but average out to an attractive effect because the orientations favor the attractive arrangements illustrated in the figure.

Which of the following is true regarding diffusion? (select all that apply)

-during diffusion, particles move from regions of high concentration to regions of low concentration -surface area and distance traveled affect the rate of diffusion -diffusion is the process in which molecules disperse in space due to differences in concentration Diffusion is the process by which molecules disperse in space in response to differences in concentration. Molecules move from regions of higher concentration to those of lower concentration, with lighter gases moving faster than heavier gases. The diffusion rate depends on several factors: the concentration gradient (the increase or decrease in concentration from one point to another), the amount of surface area available for diffusion, and the distance the gas particles must travel.

Hydrogen bonding results in:

-higher boiling points Hydrogen bonding increases a substance's boiling point, melting point, and heat of vaporization. These are all due to the strong intermolecular forces present in such a substance, making the molecules harder to separate.

Which of the below factors contribute to making hydrogen bonds so strong? highly concentrated partial charges large differences in electronegativity between the two atoms in the bond strong dispersion forces small size of the atoms

-highly concentrated partial charges -large differences in electronegativity between the two atoms in the bond -small size of the atoms The very large difference in electronegativity between the H atom (2.1) and the atom to which it is bonded (4.0 for F, 3.5 for O, or 3.0 for N), combined with the very small size of a hydrogen atom and the relatively small sizes of fluorine, oxygen, or nitrogen atoms, lead to areas of highly concentrated partial charge on these atoms. All of these factors create strong hydrogen bonds.

Mean free path increases with:

-increasing temperature -decreasing pressure

Which of the following would result in stronger dispersion forces?

-large and heavy molecules -molecules with higher polarizability In larger and heavier molecules, valence electrons are farther away from the nuclei and can more easily form temporary dipoles. Polarizability is a measure of how easy it is for another electrostatic charge to distort a molecule's charge distribution. If a molecule is polarizable, it is easily distorted and will have large dispersion forces.

-sharpen his knife to make the blade of the knife thinner and decrease the surface area -increase the force of his cut

The ideal gas law makes which of the following assumptions?

-the gas particles are constantly in random motion and have no volume -particles do not interact The ideal gas law assumes that particles are infinitely small points in constant, random motion. It does not consider the identity of the gas (whether a noble gas, a diatomic gaseous element like nitrogen, or a gaseous molecule like carbon monoxide) to affect its behavior at all. It also ignores any interactions of these particles, and assumes that they engage in perfectly elastic collisions.

Draw the Lewis structure for SeO2 (selenium dioxide). How many equivalent resonance structures can be drawn that obey the octet rule?

How many lone pairs must an atom possess to have trigonal pyramidal molecular structure?

Typically an oxygen atom with ____ covalent bond will have a formal charge of −1.

1 If oxygen has one bond and three lone pairs, that would cause a formal negative charge. For example, consider the Lewis structure for the hydroxide anion. [⋅⋅O⋅⋅⋅⋅−H]−−10 Here, oxygen has one bond and three lone pairs. Therefore, the oxygen atom "has control" of 7 electrons, (6 electrons from the three lone pairs and 1 from the O−H bond) and so oxygen has a formal charge of −1.

How many filled molecular orbitals are present in the molecular orbital diagram for H2?

1 Molecular hydrogen consists of two hydrogen atoms, each containing 1 electron in a 1s atomic orbital. Therefore, the molecular orbital diagram for H2 will have 2 electrons, both of which are placed in the lowest energy sigma bonding molecular orbital.

How many electrons does hydrogen need to gain to fill its valence shell?

According to VSEPR theory, electrons in the valence shell of a central atom form __________.

Four atomic orbitals will combine to give how many hybrid orbitals?

How many molecular geometries are possible for a compound that has a central atom with five regions of electron density (trigonal bipyramidal electron pair geometry)?

4 The molecular geometry of a compound with trigonal bipyramidal electron pair geometry is dependent on the number of lone pairs on the central atom. If all five regions of electron density are bonding pairs, then the molecular geometry is the same as the electron pair geometry, trigonal bipyramidal. If there is only one lone pair and four bonding pairs, the compound will have a see-saw molecular geometry. If there are two lone pairs and three bonding pairs, the compound will have a t-shaped molecular geometry. If there are three lone pairs and two bonding pairs, the compound will have a linear molecular geometry. Therefore, 4 different molecular geometries are possible for a compound with a central atom that has five regions of electron density.

In a Lewis structure involving iodine and fluorine, if the central iodine atom has exactly one lone pair, how many fluorine atoms must be present?

5 Iodine has 7 valence electrons, and since it is a fifth period element, it can exceed the octet rule when it binds to a more electronegative element like fluorine. Fluorine also has 7 valence electrons, but cannot exceed an octet because it is in the second period. Each fluorine atom can therefore only form a single bond to the central iodine atom, and each single bond between iodine and fluorine accounts for 1 of iodine's valence electrons. Since there is a lone pair (or non-bonding pair) of electrons on the iodine, that means precisely 2 of the 7 valence electrons are not shared with a fluorine atom, and the remaining 5 are each shared with 1 fluorine atom, so there must be 5 fuorine atoms surrounding central iodine atom.

Which is NOT a typical cation of chromium?

5+ Most transition metals will readily form 2+ and 3+ ions. The electron configuration for neutral chromium is 1s22s22p63s23p64s13d5. Chromium is a d-block transition metal, and so the valence electrons are removed from the s subshell before they are removed from the d subshell. Therefore, Chromium would lose its one s electron first and a d electron to form Cr2+, which is only stable in the absence of air. Chromium can also lose its one s electron and two more d electrons to become Cr3+, which is the most stable oxidation state for chromium. Chromium can also lose all the remaining valence electrons to become Cr6+. Chromium is seen in this oxidation state in chromium(VI) sulfide Cr2S3.

Which element does not follow the octet rule when forming a molecular compound?

B Unlike most elements with only three valence electrons, boron can form molecular compounds with some non-metals rather than only forming ionic compounds with nonmetals or alloys with metals. Because it only has three valence electrons, it can only form three single bonds by sharing its valence electrons, and does not accept another pair of electrons to satisfy the octet rule because it has a low electronegativity.

Where can you find an incomplete octect most?

B, Al, O, Br covalent compounds in groups 2 and 3 can form stable compounds in which the valence electrons are not in the noble gas structure. However, for these compounds you will find that they do form compounds that minimize formal charge. Hydrogen makes one bond (group 1). Beryllium makes two bonds (it is the only element in group 2 to make covalent compounds). The group 3 elements boron and aluminum make three bonds.

Polar molecules have a partial positive charge on one side and a partial negative charge on the other side—a separation of charge called a dipole. Which of the following molecules has this kind of a dipole? CH4 CO2 C6H6 HCl

HCl A stronger intermolecular force results when molecules have permanent dipoles. Polar molecules have a partial positive charge on one side and a partial negative charge on the other side—a separation of charge called a dipole. Consider a polar molecule such as hydrogen chloride, HCl. In the HCl molecule, the more electronegative Cl atom bears the partial negative charge, whereas the less electronegative H atom bears the partial positive charge. An attractive force between HCl molecules results from the attraction between the positive end of one HCl molecule and the negative end of another. This attractive force is called a dipole-dipole attraction—the electrostatic force between the partially positive end of one polar molecule and the partially negative end of another. Intermolecular attractions in polar molecules are stronger than the those between nonpolar molecules of similar mass, which only consist dispersion forces.

Which fact adequately explains why HCl has a higher boiling point than F2?

The overall formal charge in a molecule will always equal 1. An atom's formal charge is always equal to its actual charge. In covalent molecules, formal charges are hypothetical. all of the above

In covalent molecules, formal charges are hypothetical. In a molecule or ion containing only covalent bonds, the formal charge of an atom is the hypothetical charge that the atom would have if electrons could be redistributed evenly between atoms. In neutral covalent molecules, formal charges are always a formality—each of the atoms contained therein are electrically neutral. Conversely, in covalently bonded ions (which carry an overall charge), the formal charge of a given atom may be the actual charge on the atom, but often is not.

Li3PO4 Step 1: Identify the symbol of the cation. The cation is lithium, which is written as Li+. Step 2: Identify the formula of the anion. The anion is phosphate, which is written as PO3−4. Step 3: Use the minimum number of cations and anions needed to make the sum of all charges in the formula equal to zero. The Li+ cation has a 1+ charge and the PO3−4 has a 3− charge. In order to balance the charges, three Li+ cations are needed for every PO3−4 anion. Therefore, the formula for lithium phosphate is Li3PO4.

Given the compound name copper(II) chlorate, what is the formula of the compound? (Hint: Use the periodic table above to help you if you don't know all of the symbols by heart.)

Step 1: Determine the symbol of the cation using the first word in the compound name.Result of this step = In this case, the first word in the compound name is copper. Its symbol is Cu. Step 2: Identify the Roman numeral associated with the cation. This will tell you the charge on the cation.Result of this step = In this case, the Roman numeral associated with the copper cation is (II), signifying a charge of +2. Step 3: Identify the anion and its charge using the second word in the compound name.Result of this step = In this case, the polyatomic anion ion is chlorate. Its formula is ClO3¯. Step 4: Balance the formula so that the charge equals 0.Result of this step = Cu has a charge of +2 and ClO3 has a charge of -1. This means that for every one Cu ion, we must have two ClO3 ions. The resulting formula for this compound is Cu(ClO3)2.

The least significant figure should be estimated by reading between the smallest markings on the instrument.

To name an inorganic compound, we need to consider the answers to several questions. First, is the compound ionic or molecular? If the compound is ionic, does the metal only take on one charge value (fixed charge), or can it have multiple different charges (variable charge)? Are the ions monatomic or polyatomic? If the compound is molecular, does it contain hydrogen? If so, does it also contain oxygen? From the answers we derive, we place the compound in an appropriate category and then name it accordingly.

The majority of metals of variable charge are transition metals; most of the transition metals can form two or more different cations (each with a different charge). Ionic compounds containing these metals are named by the same method as compounds with fixed charge metals, except that the charge of the metal ion is specified by a Roman numeral in parentheses after the name of the metal. The charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+, and the two corresponding chlorides are FeCl2 and FeCl3. The simplest name, "iron chloride," will, in this case, be ambiguous, as it does not distinguish between these two compounds. In cases like this, the charge of the metal ion is included as a Roman numeral in parentheses immediately following the metal name. These two compounds are then unambiguously named iron(II) chloride and iron(III) chloride, respectively. Older nomenclature used the suffixes -ic and -ous to designate metals with higher and lower charges, respectively: Iron(III) chloride, FeCl3, was previously called ferric chloride, and iron(II) chloride, FeCl2, was known as ferrous chloride. Though this naming convention has been largely abandoned by the scientific community, it remains in use by some segments of industry. For example, you may see the words stannous fluoride on a tube of toothpaste. This represents the formula SnF2, which is more properly named tin(II) fluoride. The other fluoride of tin is SnF4, which was previously called stannic fluoride, but is now named tin(IV) fluoride. Note that this older system of naming uses the Latin roots of the metals involved.

What happens to the potential energy between two hydrogen atoms as they approach each other to form a covalent bond?

The potential energy decreases as the hydrogen atoms approach each other, but will increase if they get too close. Potential energy decreases as two hydrogen atoms approach each other to form a covalent bond. However, if the atoms get too close their positively charged nuclei begin to repel each other, which increases the potential energy between the atoms. Thus we define bond length as the distance at which the lowest potential energy is achieved. This an illustration of the Goldilocks principle: the distance between atoms must be just right.

Which of the following statements are true?

The sum of all formal charges in a neutral molecule must be zero. The sum of all formal charges in an ion must equal the charge of the ion.

What happens to the 1s orbitals on the hydrogen atoms as they approach to make a covalent bond?

They begin to overlap in a direct or head-on fashion. It is this overlapping of orbitals that allows the electrons to interact with both nuclei.

Which of the following is true of covalent bonds?

They have lower melting points than ionic bonds. They have lower boiling points than ionic bonds. They do not conduct electricity or heat well. Covalent compounds generally have much lower melting and boiling points than ionic compounds because the attraction between molecules (which are electrically neutral) is weaker than that between electrically charged ions. Therefore, they do not conduct electricity or heat well.
