Water
how many oxygen atoms are in a molecule of water?
1
how many hydrogen atoms are in a molecule of water?
2
maximum number of bonds that one molecule can share is...
4
where is the majority of negative charge on the water molecule?
Around the oxygen
what do the solid lines between the small and large circles represent?
Covalent bond
Hypotonic
Having a lower concentration of solute than another solution
Hypertonic
More dissolved stuff; less water
what kind of charge would the oxygen atom have compared to the hydrogen atom?
Negative
what kind of charge would the hydrogen atom have compared to the oxygen atom?
Positive
What arrangement of electrons would result in a nonpolar molecule?
The bonding in the molecules have to be equally shared between the atoms
What type of molecules make up water?
The scientific term for water is H2O. This means that in each water molecule there is two hydrogen atoms and one oxygen atom.
Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?
They cannot mix
capillary action
adhesion of water to glass (or paper etc) that causes water to rise against gravity
What kind of charge would the hydrogen atoms have compared to the oxygen?
higher positive charge
the small unshaded circles in model 2 are?
hydrogen
describe the arrangement of the water molecules in model 2 with one another
hydrogen atom is attracted other atom of water molecules
Why is water good for you?
keeps you hydrated, flushes fat, helps liver and kidney function.
describe the cause of the attractions between molecules of water
opposite charges atract
How many hydrogen atoms are in a molecule of water?
two
according to model 2 what is represented by the dotted lines?
weak attraction
