Balance Pro 177 g
Good Balance 180 g
Exacto-Balance 1770 g
a Based on this additional information, does rock C have a mass larger, smaller or the same as rock B, or is it impossible
to tell? Explain your reasoning

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.

The answer is a. stable, hope i ya
