"Which" implies choices... Where are they??
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
Endothermic reactions favor the reactants in a chemical reaction.
A reactant is an "ingredient" in a chemical reaction; it is a substance you have at the beginning of a reaction. A product is what gets produced in a chemical reaction; it is a new substance you did not have before. Reactants yield products.
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
The reactants
In a chemical equation, the elements/compounds listed on the left side, are the reactants. The right side contains the products of the reaction. eg, 2H2 + O2 = 2H2O. The Hydrogen combines with the Oxygen to from the product, Water.
The product is hydrogen. to test for hydrogen, take a lighted match or a splint and bring it near the place where you think there is hydrogen and if you hear a squeaky "POP!" there is hydrogen there
The chemical equation Mg + H2S -> MgS + H2.
The substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.
the coefficients of a balanced reaction
reactants
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
Reactants- The substances used up in a reaction. Products- The new substances made.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
reactants are on the left and the products are on the right
