The balloon’s volume needs to be 1.05 L, at a pressure of 745 mmHg and a temperature of 23 °C. Assuming that your exhaled breath is 100% carbon dioxide, how many grams of the gas must you exhale?

Solubility would be your answer.

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.
