In the following acid-base equilibria of weak acids in water, label the acid (A), the base (B), the conjugate acid (CA), and the conjugate base (CB). HCIO,(aq) + H,O(l) = H,O*(aq) + ClO, (aq) ******* H₂CO3(aq) + H₂O(1) = H₂O+ (aq) + HCO3(aq) H₂O(1) + CH3NH3(aq) → CH3NH₂(aq) + H₂O+ (aq) O $0 CH3COOH(aq) + H₂O(1) ⇒ CH₂COO¯(aq) + H₂O+ (aq) Answer Bank CA CB

A1.

If a small amount of HCI (aq) is added to 0.10 M CH3COOH (aq), the equilibrium concentration of acetate ions increases the Ka becomes larger the equilibrium concentration of acetic acid decreases no change occurs the equilibrium concentration of CH3COO^- (aq) is decreased

During hot summer months, high altitude lakes are more susceptible to "fish kills" (where all od the fish in the lakes die around the same time) than low altitude lakes. Given that fish require dissolved O2(g) to survive, which of the following could explain this phenomenon?

Hi, Write an equilibrium expression for chemical equation involving one or moresolid or liquid reactants or products, thanks. CO32-(aq)+ H2O(l) <-----> HCO3-(aq) + OH-(aq)

The equilibrium constant for the acid ionization of mercaptoethanol (HSCH2CH2OH) is HSCH2CH2OH(aq) = H+(aq) + SCH2CH2OH-(aq)               k= 1.91 x 10-10 Which of the following is/are true regarding this equilibrium?
