what is chemical equation
Answers
a process in which a substance change from one form to another form is called reaction. chemical reactions are usually categorized by chemical change in which reactants change chemically in another product.
Chemical equation is any reaction in which substance change chemically as well as physically.
The atoms and molecules that interact are called the reactants. The atoms and molecules produced by the reaction are called products.
Chemists use a shorthand notation called a chemical equation to indicate the reactants and the products.
In this notation, the reactants are listed on the left side, the products are listed on the right side, and the reactants and products are separated by an arrow showing which direction the reaction proceeds.
While many chemical equations show reactants forming products, in reality, the chemical reaction often proceeds in the other direction, too. In a chemical reaction and a chemical equation, no new atoms are created or lost (conservation of mass), but chemical bonds may be broken and formed between different atoms.
