What is the minimum potential difference (voltage) when a MgCl2 solution undergoes electrolysis with a platinum electrode? E h2o, h2 = -0,40V E O2,h2o = +1,23V; > E Mg2+,Mg = -2,37V;E Cl2; Cl- = +1,36V

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
