If you have 4 moles of Os(NO3)2 and 6 moles of H2O do you have the right stoichiometric ratio, or is there one reactant in excess and other other limiting? How can you tell? The balanced equation:
2Os(NO3)2 + H2O -> Os2O3 + 4NO2 + H202

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?
