Katheryn was mixing a substance with acid for an experiment. The acid completely dissolved into the substance. She wrote the following in her journal: There were bubbles of citric acid in the new substance. Is this an observation or inference? Ik this is pretty easy, but I would like to confirm my 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.
