The reactant that gets used up first.

What is kinetic molecular theory?

Tiny particles form all matter, and they are constantly in motion.

Define diffusion vs. effusion.

- Diffusion: particles moving through a space (perfume spreading through a room.)


- Effusion: particles moving through a hole (leak in a balloon.)

Barometer.

What is standard pressure?

- 1 atm


- 101.3 kPa

What happens to volume as temperature increases (pressure stays the same)?

According to Charles' Law, it increases as well.

Tell what all of the letters in PV = nRT stand for.

P = Pressure


V = Volume


n = Moles


R = Gas Law Constant based on Pressure


T = Temperature in Kelvin

What is the volume of one mole of gas at STP?

22.4 Liters.

Define Inhibitor vs. Catalyst.

- Inhibitor: stops the effects of a catalyst on a reaction.


- Catalyst: speeds up a reaction by lowering the activation energy.

Red.

What are the suffix rules for naming acids?

- Binary: hydro___ic acid


- Ternary:


- (ite): ___ous acid


- (ate): ___ic acid

How do you determine if a compound is a base?

If the compound contains hydroxide (OH,) then it's a base.

Define Bronstead-Lowry acid and base.

- Acid: A compound that donates hydrogen.


- Base: A compound that accepts a hydrogen.

The pH of a solution with a concentration of 0.090 M. HCl is what?

pH = 1.0

pH = - log [H3O]

What is there a difference between an ionic and covalent compound.

- Ionic: Electrons are given or taken.


- Covalent: Electrons are shared.

How many calories are needed to raise the temperature of 35g of water from 22.5 •C to 35 •C?

440 calories.

- Q = mC🔺T


- C = 1cal / g•C

What is a dilute vs. concentrated solution?

- Dilute: A solution has a low amount of solute.


- Concentrated: A solvent has a high amount of solute.

What are colligative properties?

Properties that depend on the amount of substances in the container and not what they are.

Name three colligative properties.

- Freezing point


- Boiling point


- Vapor pressure

What is a catalyst?

Catalyst: Speeds up a reaction by lowering the activation energy without being used up.

How can you tell the difference between monoprotic, diprotic, and triprotic acids?

- Monoprotic: 1 hydrogen.


- Diprotic: 2 hydrogens.


- Triprotic: 3 hydrogens.

What is the Law of Conservation of Mass?

Matter cannot be created or destroyed.

What is the molarity of a solution that contains 6.0g of NaOH in 250mL of water?

0.6M.

What happens when vapor pressure of a liquid is equal to atmospheric pressure?

This is the boiling point.

How does a catalyst speed up a reaction?

It lowers the activation energy required for the reaction to take place.
