A buffer solution is made up of acetic acid ( CH3COOH) and sodium acetate (NaCH3COO). The major equilibria in the buffer system are represented above. Which equilibria could be used to support the claim that the addition of a small amount of NaOH to the buffer will result in only a very small change in pH?

An alkaline battery produces electrical energy according to the following equation. zn(s) + 2 mno2(s) + h2o(l) zn(oh)2(s) + mn2o3(s) (a) determine the limiting reactant if 17.5 g zn and 31.0 g mno2 are used. (type your answer using the format ch4 for ch4.) (b) determine the mass of zn(oh)2 produced. _ g
