Question

what is chemical equation why is it necessary to balance an equation ​

Answer 1

Answer :

Definition

Chemical Equation :- They are the symbolic and mathematical representation in the form of symbols and formulas. Here reactants are on right side and products are on left side.

Example

Chemical equation

CH4 + O2 →  CO2 + H2O

2nd Part  

Chemical equations need to be balanced in order to satisfy the law of conservation of matter, which states that in a closed system matter is neither created nor destroyed.

Balanced Chemical equation

CH4 + 2O2 →  CO2 + 2H2O

                                                                                                                       

Answer 2

Answer:

Explanation:

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
