Moles
1.How is molar mass calculated and why is it useful?
Molar mass is calculated by going to the periodic table finding each mass of each element in the compound then adding them all up based on how many of those elements are in the compound.
2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations.
Mole is considered the unit for amount in chemistry other units that are equivalent are atoms, formula units, and molecules.
Gas Laws
3.How is the combined gas law used to calculate differences in pressure, temperature and/or volume for a fixed amount of gas?
This is a combination of three different gas laws that give variables for pressure, temperature, and volume that can find the amount of a …show more content…
The ideal gas law is shown as PV=nRt, where R is considered the gas constant in the equation or the problem that is being asked in a question.
Solutions
5.What factors affect the rate at which a solution dissolves?
When you heat or cool the solution it will increase when heated and decrease when cooled, also you can break the pieces of the solvent into smaller pieces and it will dissolve faster. As well as adding solvent will decrease the rate of dissolving.
6.What are the various parts of a solution?
There is the solvent which has the greatest abundance and there is the solute which is what is being dissolved.
7.Distinguish between an unsaturated, saturated, and supersaturated solution.
Saturated is when it does dissolve in the solvent, supersaturated is when the solute does not dissolve in the solvent and unsaturated is when some of the solute dissolves in the solvent.
Acids and Bases
8.What occurs during a neutralization reaction (process)?
When a single salt and water are formed from an acid and base reaction.
9.How does the pH scale and the concentration of a solution related?
When the pH increases the concentration decrease and vise versa.
