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 MgCl 2 and H 2 . (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, MgCO 3 , required to produce 283 g 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, C 2 H 2 , in an excess of oxygen. (e) The number of moles and the mass of barium peroxide, BaO 2 , needed to produce 2.500 kg of barium oxide, BaO ( O 2 is the other product.) (f) The number of moles and the mass of required to react with H 2 O to produce 9.55 g of 45. Determine the number of moles and the mass requested for each reaction in Exercise 4.44.

The single largest use of phosphoric acid is in the production of fertilizer. How many grams of phosphoric acid (with excess NH3) are required to produce 800 g of (NH4)2HPO4, a common fertilizer?
Methylhydrazine, N2H3CH3(l), is used with the oxidizer dinitrogentetroxide, N2O4(l), to power the steering rockets of theSpace Shuttle orbiter. The reaction of these two substancesproduces N2, CO2, and H2O. Write a balanced equation forthis reaction.
