Oh I see you answered that, So , it is incorrect to add 2H to balance H2 in a basic solution... ? Although all the first steps are the same as used in acidic solution?

chemistry
my question is about whether I have to add water or just H to firstly balance the second half reaction either 2e+2H2O--->H2+2OH OR 2e+2H-->H2 which one is correct for a basic solution reaction ? thanks a lot

chemistry
In the REDOX reaction in basic solution Zn-->Zn(OH)4+H2 I know that the first half reaction is 4H20+Zn-->Zn(OH)4 +4H+e but the second one is either 2e+2H2O--->H2+2OH (WHICH IS THE ANSWER GIVEN ON THE WORKSHEET) OR 2e+2H-->H2 I think both leads to the same answer= ...
