gases are most soluble in liquids

salts are most soluble in liquids

there are fewer collisions of gas particles

solubility of gases is not affected

kinetic collision theory states:

a chemical reaction will occur when particles collide with sufficient energy and orientation

an increase in moles will increase pressure

matter is not created or destroyed in a chemical reaction

In the mason jar, liquid water and water vapor were at equilibrium. This would indicate that...

the rate at which liquid water becomes water vapor and water vapor condenses is equal

the mass of liquid and vapor water were equal

the number of water gas and liquid water particles were equal

the concentration of liquid water and water vapor is equal

if it gets warmer more oxygen will be produced

If it gets colder, the reaction will shift to the right

if it gets warmer, the reaction will shift to the left

if it gets colder, more sugar will be produced

What happens when the pressures of carbonic acid (product) and water and carbon dioxide (reactants) become constant and level?

the rates of forward and reverse reaction become equal

concentrations will remain constant but the reaction will continue

What describes a solution of NaOH?

the solution has a pH of more than 7

the solution has a pH of less than 7
