Explain how the Law of Conservation of Mass is applied in the balanced equation illustrated below. 2Na(s) + 2 H2O(l) to form 2 NaOH(aq) + 1 H2(g) please help, I need to turn it in right now!! DO NOT SEND ANY VIRUSES OR I WILL REPORT YOU

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
