Write the balanced equation, then outline the steps necessary to determine the information requested in each of the following
a) the number of moles and the mass of Mg required to react with 5.00 g of HCl and produce MgCl2 and H2
b) the number of moles and the mass of oxygen formed by the decomposition of 1.252 g of silver(I) oxide.
c) the number of moles and the mass of magnesium carbonate, MgCO3, required to produce 283g of carbon dioxide. (MgO is the other product)
d) the number of moles and the mass of water formed by the combustion of 20.0 kg of acetylene, C2H2, in an excess of oxygen
e) the number of moles and the mass of barium peroxide, BaO2, needed to produce 2.500 kg of barium oxide, BaO (O2 is the other product)
