Hydrocarbons are organic compounds composed entirely of hydrogen and carbon. A 0. 1647 g sample of a pure hydrocarbon was burned in a combustion apparatus to produce 0. 4931 g of CO2 and 0. 2691 g of water. Determine the empirical formula.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
