chemistry exam quarter 3

which of the following choices is the equilibrium constant of a reaction

Keq=[products]/[reactants]

what is a base

substance that increases the concentration of OH- ions in solution

what would happen if the equilibrium of a weak acid dissociation reaction were upset

the reaction would shift to balance the change

what do all acids have in common

they all contain hydrogen

what is the triple point on a phase diagram

a point indicating three phases in dynamic equilibrium

what is true of dynamic equilibrium

all changes to a system cancel out.

what are phase change processes taking place when a substance is in equilibrium between liquid and gas phases

evaporating and condensing

what happens when a base dissolves

it increases the concentration of OH- in a solution

what is the equilibrium constant of a reaction

it is the ratio of the number of products to the concentrations of reactants

what is always true of a weak acid

it only partly dissociates in solution

what is true if liquid and gas are in equilibrium

liquid molecules forming a gas and gas molecules forming a liquid are equal in number

what happens if more product is added to a system at equilibrium

more reactants will form
