The following balanced equation shows the decomposition of ammonia (NH3) into nitrogen (N2) and hydrogen (H2). 2NH3 → N2 3H2 A quantity of NH3 decomposes to produce 0. 0351 mol N2. How many moles of H2 are produced? 0. 0351 mol H2 0. 0117 mol H2 0. 105 mol H2.

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?
