my class did a metal activity series lab where we added calcium to 8 different solutions. We have to write the net ionic equations for each reaction but im stuck getting started on them. Ca(s) + Ca(NO3)2(aq) = ? my guess Ca(s) + Ca(NO3)2(aq) + 2H2O(l) --> Ca(OH)2 + H2(g) + Ca(NO3)(aq) This one reacted in the lab. I also remember gas being formed so do I have to include water in the equation?? but i dont know what the equation is. Another one is Ca(s) + FeSO4(aq) = im guessing its CaSO4(aq) + Fe(s) ? again there was gas formation but there is no gas in the equation? Would really appreciate the help.
