Correct compound Name for Carbon Dioxide
CO2
What are some examples of weak bases.
Calcium Hydroxide and Magnesium Hydroxide
What is the one common characteristic of a Organ Compound?
Carbon
What are Proton and Neutrons?

List 4 ways to speed up the rate of a reaction.
Concentration, Pressure, Temperature, Catalysts
Organic compounds are used in biomanufacturing because they are cheap.
False
To increase the amount of gas that will dissolve in a liquid, increase the temperature.
False
On the chemical diamond what does the color red stand for?
Flammability
What are two major dangers of Organic Compounds?
Flammable and Toxic
What is a first aid responds to ammonia solution that has come in contact with skin or eyes?
Flush with water and get immediate medical attention
What is the Chemical symbol for water?
H20
What is the Chemical symbol for Hydrogen Peroxide?
H202
What is the Chemical symbol for Hydrochloric Acid?
HCL
On the chemical diamond what does the color Blue stand for?
Health
What is another common oxidizing agent?
Hydrogen H2O2
What do you need to do to increase the amount of gas rate that has dissolved in a liquid?
Increase the pressure
Distillation
Is the method used to separate lipuids with different boiling points from a mixture
Chromatography
Is the most common separation method, is the process of using a solid surface with particular molecules, so that when components in a solution pass over the surface, they separate from each other. Look for key word resin
liquid Extraction
Is the process of adding a different solvent to a solution, a solvent that will pull a particular solute from the solution.
Evaporation
Is the process of changing a liquid to a vapor or gas
Crystaliztion
Is the process of separating a solute from a liquid solution by increasing the concentration of that solute until the solvent is not able to absorb any more.
Precipitation
Is the process that separates a solid solute from a solution by changing the solute to a precipitate. Example: If you add vinegar to milk or beaten eggs, the resulting clumps in the milk or eggs are a precipitate of the proteins.
Filtration
Is the process that uses a mechanical device to physically separate solid particles from a solution.
What is the Chemical symbol for Ammonia?
NH3
Correct compound Name for Sodium Chloride
NaCL
Correct compound Name for Sodium Bicarbonate
NaHCO3
Correct compound Name for Sodium Hydroxide
NaOH
What charge is a Electron?
Negative
What charge is a neutral?
Neutron
Does an MSDS tell you how to safely carry out reactions between different chemicals?
No
What type of compound is a Ketones?
Organic Compound (containing oxygen)
When methane is burned, what is the oxidizing agent in the reaction?
Oxygen
What is the most common oxidizing agent?
Oxygen O2
What charge is a Protons?
Positive
Exothermic
Produce energy and release it into the environment
On the chemical diamond what does the color yellow stand for?
Reactivity
Endothermic
Requires energy from the environment to keep going
On the chemical diamond what does the color white stand for?
Special (many types of special Hazards)
Atom
The fundamental building blocks of an element
To change the pH of a solution from 11 to 4, you should adjust by adding an acid.
True
When mixing acids and water, the acid should be added to water because water is a good absorber of heat.
True, Do as you oughter, pore acid into water
Conductivity
Uses electrical current to check ion concentration
Can a molecule or an atom lose its electrical charge?
Yes

Yes
Does an MSDS tell you what PPE you should wear?
Yes
Does an MSDS tell you what a chemical looks like?
Yes
