Best ResponseYou've already chosen the best response.1\[Au+(NO_{3})^{ (1)}> NO _{2}+Au^{+2}\] now first of all balance hydrogen and to balance hydrogen add H+ ions on both the sides or the lagging side then balance Oxygen by adding H2O on the lagging side

Best ResponseYou've already chosen the best response.1new equation would be \[Au+NO _{3}^{1}>NO _{2}+Au^{+2}+H _{2}O\] now as we can see that on the product side there are two extra oxygen , you have to add 2H+ ion on reactant side and rest of the elements are balanced

Best ResponseYou've already chosen the best response.1adding two H+ ion \[2H^{+}+Au+NO _{3}^{1}>NO _{2}+Au^{+2}+H _{2}O\] now you can see that everything is balanced , you have to balance charge, next

Best ResponseYou've already chosen the best response.1on the left side total charge is +1 and on the right side total charge is +2 but we cant add +ve ion so to balance charge we will add electron on the right side to make it equal to +1 and after that you can do it :)
