3.00x108 m/s
What is the ideal gas equation?
PV=nRT
What is a solution?
A solution is a homogeneous mixture of 2 or more pure substances.
What are the factors affecting solubility?
1. Temperature
2. Surface Area
3. Stirring
4. Pressure
What is an ionic compound made up of?
Ionic compounds involve ions, so they are typically the combination of a metal and a nonmetal
How many valence electrons do all noble gases have?
8
How do you convert from Celcius to Kelvins?
Add 273.
What is a solvent?
The substance present in the greatest amount in a solution.
What is molarity?
Molarity is the concentration of a solution as the number of moles of solute in 1 liter of solution.
What branch of chemistry deals with the study of most carbon containing compounds?
Inorganic chemistry
What equation do you use to solve for wavelength?
Wavelength = speed of light/frequency
What does "n" stand for in the ideal gas equation?.
Number of moles
What is a solute?
A pure substance dissolved in solvent.
Why does temperature affect molarity?
Temperature affects volume; volume affects molarity.
What is applied science?
Applied science is a discipline of science that applies existing scientific knowledge to develop more practical applications, like technology or inventions.
Which kind of bond "shares" electrons?
Covalent bond (or multiple bond)
How do you convert from torrs to atm?
Divide by 760.
Which of the following is the most unstable solution: saturated, unsaturated, or supersaturated?
Supersaturated. If you scratch the side of the container holding the solution, crystals will probably form.
What do you need to know to determine the grams per solute?
You need to know the molarity, volume, and molecular weight.

Ionic Bonds
What number does the letter R stand for in the ideal gas equation?
0.08206 L-atm/mol-K
What does it mean to "sulvate" something?
As a solution forms, it pulls solute particles apart and surrounds them.
What is the formula for calculating molarity?
Moles of solute/liters of solution
