The initial substances in a chemical reaction are called reactants.
These substances are called products in English.
The substance (or substances) initially involved in a chemical reaction are called reactants or reagents
Reactants: the initial substances in a chemical reaction Products: the final substances in a chemical reaction Catalyst: a stimulator of a chemical reaction, not directly involved in the reaction, remain unchanged
A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products involved in the reaction and the stoichiometry of the reaction. It provides information about the type and amount of substances involved in the reaction.
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
Chemical change.
Substances initially present in a chemical reaction that are consumed during the reaction to make products are called "reactants".A "reagent" is a substance or compound that is added to a system in order to bring about a chemical reaction or is added to see if a reaction occurs.Although the terms reactant and reagent are often used interchangeably, a reactant is more specifically a "substance that is consumed in the course of a chemical reaction".Solvents and catalysts, although they are involved in the reaction, are usually not referred to as reactants.
The new and different substances formed as a result of a chemical change (reaction) are the products of the reaction.
A chemical equation represents a chemical reaction in which reactants are converted into products. It shows the chemical formulas of the substances involved in the reaction and the proportions in which they combine.
In a chemical reaction, the total mass of the substances involved stays constant. This is known as the law of conservation of mass.
