Question

define reactants and products with examples class 10

Answer 1

Answer:

Atoms or ions or molecules which react to form a new substance are called reactants; the new atoms or molecules formed are products. A chemical reaction follows the law of conservation of mass. That is no atom is destroyed or created but only a new product is formed from reactants.

For example: When two sodium atoms react with two chlorine atoms(reactants), they give a completely new compound (product) i.e. sodium chloride (two atoms).

Answer 2

Answer:

The substance(s) to the left of the arrow in a chemical equation are called reactants. 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.

For ex - 2Mg + O2 --------> 2MgO

Here, Mg ( magnesium) and 02 (oxygen) are reactants they react with each other and form 2MgO (magnesium Oxide) so 2Mgo is the product
