How many atoms are in 75.4 moles of Copper? How many atoms are in 75.4 moles of Copper?

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 .

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
