Reacttant
WebA reactant is a chemical compound that directly participates in a reaction. Usually it's there at the beginning but not at the end, presuming the reaction runs to completion. A reagent is a chemical compound present during a reaction, but not consumed by it. WebFeb 27, 2024 · Explanation: The term "product" would normally be used to describe a substance that is produced as a the result of a chemical reaction. However, heat is not a substance, it is a term used to denote the flow of energy (in this case from the reaction medium to the external environment).

WebOne reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent. If the amount of B present is less than required, then B is the limiting reagent.
