Find the concentrations of all species in a 1.0 liter flask if 0.72 mol H2 reacts with 0.72 mol CO2, until the equilibrium CO2(g) + H2(g) CO(g) + H2O(g) is reached. K = 0.34 at the existing temperature.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
