Answers
Explanation:
Reactants Products
1. The substances used as starting materials and which react with one another are reactants. 1. The substances which are formed as a result of reaction are products.
2. Example: In this reaction Mg and O2 are reactants. 2. Example: In this reaction MgO is a product
Answer:
(a) Reactants and products
Reactants
The substances that react with one another are called reactants.
Reactants are written on the left hand side of equation.
Products
The new substances formed are called products.
Products are written on the right hand side of equation.
(b) A balanced and an unbalanced chemical equation
Balanced chemical
A balanced chemical reaction is the one in which the number of atoms of each element on the reactant side is equal to the number of atoms of that element on the product side.
Ex- H2 + Cl2 → HCl
Unbalanced chemical
Number of elements on reactant side are not equal to the number of elements on product side.
Ex - H2 + Cl2 → 2HCl
Explanation:
A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
