The number of atoms molecules or formula units of a reactant or a product in a balanced chemical equation is the coefficient of that species e g the 4 preceding h 2 o in equation 4 1 1. Chemical equations have reactants on the left an arrow that is read as yields and the products on the right.

They are shown on the right hand side of the reaction equation.

What are reactants and products in a chemical equation. They are generally more stable molecules than the reactants. The substance s to the right of the arrow are called products. A chemical reaction is the process in which one or more substances are changed into one or more new substances.

You can t change one element into another in a chemical reaction that happens in nuclear reactions. Reactants and products in chemical reactions in a chemical reaction substances elements and or compounds called reactants are changed into other substances compounds and or elements called products. Specifically it gives the relative amounts of reactants and products consumed or produced in a reaction.

A product is a substance that is present at the end of a chemical reaction. In the case of the reaction between zn and h2so4 the products are zinc sulfate and hydrogen gas. A chemical equation consists of reactants products and an arrow showing the direction of reaction.

The products of a reaction are the chemicals that are formed from the break down and rearrangement of the reactants. A reactant is a substance that is present at the start of a chemical reaction. The representation of a chemical reaction in the form of symbols substances is known as chemical equation.

In the equation above the zinc and sulfur are the reactants that chemically combine to form the zinc sulfide product. The reactants for photosynthesis are light energy water carbon dioxide and chlorophyll while the products are glucose sugar oxygen and water. The equation in which number of atoms of all the molecules is equal on both sides of the equation is known as balanced chemical equation.

If a chemical reaction has an arrow that points both left and right then substances on both sides of the arrow are reactants as well as products the reaction proceeds in both directions simultaneously. In a chemical equation reactants are listed on the left side of the arrow while products are on the right side. Chemical reactions are represented by chemical equations.
