Hydrogen sulfide and oxygen react to form sulfur dioxide and water, like this: 2H2Sg + 3O2g → 2SO2g + 2H2Og. Suppose a mixture of C2H2, O2, CO2, and H2O has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also...

part B and D???
Review I Constants Learning Goal: Correct To understand how to use stoichiometry to convert between quantities of reactants and products in chemical equations. Stoichiometry describes the quantitative relationships among the reactants and products of a balanced reaction by directly comparing mole ratios. Stoichiometry can be used to convert mass, number of moles, or number of particles...
