Final

Question 1

4 main factors that describe a gas

Answer 1

temperature
volume
pressure
number of particles

Question 2

what causes pressure in a gas?

Answer 2

collisions of gas particles against the walls of the container

Question 3

List at least 3 scientific errors(will make percent yield smaller)

Answer 3

1. bad lab equipment
2. reactants are not pure
3. environmental circumstances
4. not enough time

Question 4

What is the difference between a real and ideal gas?

Answer 4

Ideal-doesn’t lose energy when moving around, larger volume

Real-Loses energy when moving around

Question 5

Difference between effusion and diffusion?

Answer 5

Diffusion-no barrier

Effusion-small holes

Question 6

process of dissolution for a solid in a liquid

Answer 6

solute particles surrounded by solvent

solute particles are pulled away and into solution

Question 7

factors that effect the rate of dissolution

Answer 7

• mixing
• temperature
• surface area

Question 8

List and explain the three main theories of acids and bases

Answer 8

Arrhenius-balance between H+ and OH- concentration

Brostead Lowry- transfer of protons (h+)

Lewis- transfer of electron pairs

Question 9

Difference between specific heat and heat capacity

Answer 9

Specific Heat-amount of heat needed to raise the temp by 1 gram of a specific material by 1 degree

Heat Capacity-Amount of heat needed to raise the temperature of an object of a specific material
