How much excess reagent remains if 24. 5 g of Cobalt Oxide (CoO) reacts with 2. 58 g of Oxygen? CoO + O2 --> Co2O3

The correct answer is "atomic weight".

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
