uestion A12 ) i. When ammonium carbonate, (NH4)2CO3 is heated, it decomposes into ammonia gas, carbon dioxide gas, and water vapor. (assume the reaction proceeds to completion). Write the complete balanced equation for this reaction. ii. How many grams of NH3 are produced when 122 g of solid (NH4)2CO3 is heated at high temperature? Give your answer to 3 significant figures.

Small quantities of oxygen can be prepared in the laboratory by heating potassium chlorate, KClO3(s). The equation for the reaction is   2KClO3⟶2KCl+3O2 Calculate how many grams of O2(g) can be produced from heating 12.2 g KClO3(s).

A sample of a substance (containing only C, H, and N) is burned in oxygen.3.382 g of CO2, 2.307×10-1 g of H2O and 7.685×10-1 g of NO are the sole products of combustion.What is the empirical formula of the compound?

Ethylene (C2H4) reacts with molecular hydrogen according to the equation below. C2H4 (g) + H2 (g)- C2H6 (g) If you start with equal masses of both reactants, which of the statements below is true? The ethylene is the limiting reactant. The hydrogen is the limiting reactant. There is no limiting reactant - both substances are present in the necessary ratio for them to react completely. We cannot determine the limiting reactant without first knowing the exact masses of each substance.
