What is can chemistry be one-sided?

Chemistry cannot be one-sided as it involves interactions between two or more substances. In any chemical reaction, the reactants and products have to interact with each other to form new substances. The way in which the substances interact depends on their properties and the conditions under which the reaction takes place. Thus, chemistry is always a two-way process, and the outcome of a chemical reaction depends on the relative amounts and properties of each of the reacting substances.
