Case 1: A chemical equation is the representation of chemical change in terms of symbols and formulae of reactants and products. The substances which react are written on the left hand side of the arrow and are termed as reactants while the substances produced as result of reaction are called products and are written on the right hand side of the arrow. The arrowhead shows the direction of the reaction. A chemical equation in the whcih the number of atoms of each element on reactant side is equal to that on the product side is said to be balanced.

Among the following the correct balanced equation is

A

`3Fe+4H_(2)OtoFe_(3)O_(4)+4H_(2)`

B

`Zn+HCl to ZnCl_(2)+H_(2)`

C

`N_(2)+H_(2)toNH_(3)`

D

`C+O_(2)toCO`

Text Solution

Verified by Experts

The correct Answer is:
A
Explanation: A balanced chemical equation occurs when the number of atoms involved in the reactant side is equal to the number of atoms is products side.
