I have been trying to balance this equation... I have balanced all the elements on both sides of the equations besides H's and O's and once I balanced the H's, I can't seem to balance the O's to make the whole equation equal! Step-by-step would be greatly appreciated! ?Cu(s) + ?HNO3(aq) -> ?Cu(NO3)2(aq) + ?H2O(l) + ?NO(g) And this is the same thing too for this equation, somehow I get stuck with the H's. Am I doing the process wrong? S2Cl2 + NH3 -> N4S4 + NH4Cl + S8 Thank you so much in advance! C
