HELP PLEASE Use the following steps to balance the redox reaction below:
Mg + Au+ Mg2+ + Au

a. Write the oxidation and reduction half-reactions. Make sure each half-reaction is balanced for number of atoms
and charge. (3 points)

b. Multiply each half reaction by the correct number in order to balance charges for the two half reactions

c. Add the equations and simplify to get a balanced equation

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
