How do you solve for moles of a substance?
n=m/mm

What is a Colloid and what is one example of one?
A solution of intermediate sized particles. Milk
100
What is the process of attraction and association of molecules of a solvent with molecules or ions of a solute?
Solvation, commonly called dissolution
100
In winters, a variety of chemical salts are added to the ice on sidewalks and roads to melt it. Which colligative property is involved in the process?
Freezing Point Depression

How many Skywalkers are in the Star Wars series?
3
200
The moles and molality of a solution is known. How can you solve for the kg of solvent given m=n/kg
kg=n/m
200
What is light scattering by particles in a colloid or else particles in a very fine suspension?
The Tyndall Effect
200
What is dilution?
It is the process of decreasing the concentration of a solute in solution, usually simply by mixing with more solvent.
200
In osmotic pressure does the concentration go from low to high or high to low?
High to Low
200
What Goes up but never goes down
Rain
300
What is the dilution equation?
M1V1=M2V2
300
What is the difference between a homogeneous mixture and a heterogeneous mixture?
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases; solid, liquid, and gas
300
When solute is added to boiling water what happens to the vapor pressure?
The Vapor Pressure is Lowered
300
How can a pants pocket be empty and still have something in it?
It could have a hole in it!
400
What equation would you use if, you were given the mass of the solute and the mass of the solution?
Percent by Mass Equation
400
What type of mixture if left still, the solid pieces will separate from the liquid and either fall to the bottom or rise to the top?
Suspension
400
What are the four colligative processes?
Vapor pressure reduction Freezing point depression Boiling point elevation Osmotic pressure

Mary’s father has 5 daughters – Nana, Nene, Nini, Nono. What is the fifth daughters name?
Mary!
500
If M=n/L and I knew the molarity and the liters of solvent, then how would I solve for the moles?
n=M*L
500
What is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the quick atoms or molecules in the gas or liquid
Brownian Motion
500
Is vapor pressure of a solvent lower or higher with a non-volatile solute?
Lower
500
What is so delicate that saying its name breaks it?
silence
