A buffer solution based upon ascorbic acid (H2C6H6O6) was created by treating 1.00 L of a 1.00 M ascorbic acid solution with NaOH until a pH of 3.625 was achieved (assuming no volume change). To this buffer 1.150 moles of NaOH were added (assume no volume change). What is the final pH of this solution

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
