. Which equation describes the half-reaction that occurs at the cathode during the electrolysis of water?

2H2O(l) + 2e– → H2(g) + 2OH–(aq)

2H2O(l) → 2H2(g) + O2(g)

4H+(aq) + 4OH–(aq) → 4H2O(l)

O2(g) + 4H+(aq) + 4e– → 2H2O(l)

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
