definition of equilibrium - Answer-chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate if K<<1 - Answer-reaction is reactant favored, reactant predominates at equilibrium, lies to the left if K>>1 - Answer-reaction is product favored, products predominate at equilibrium, lies to the right Define Q - Answer-The reaction quotient, gives the same ratio as equilibrium expression, but for a system not at equilibrium Q<K - Answer-reaction ...

Acids And Bases Latest Exam Update Test 2024. What is an acid or a base? - correct answer An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water. What do you get when you mix an acid and a base? - correct answer It depends on what type...
