In a chemical reaction, the total mass of the products . A can be greater or less than the total mass of the reactants B is always less than the total mass of the reactants in an open system C must be less than the total mass of the reactants D must always be the same as the total mass of the reactants

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
