Question

N²+H²=NH³ balance the chemical equation​

Answer 1

$\mathfrak{{\colorbox{cyan}{{\colorbox{h}{Answer}}}}}$

In order to balance the above chemical equation

apply hit and trial method

$\sf \:{N_2 + \:H_2 \: \: ➪ \: NH_3}$

On LHS we have 2 atoms of Nitrogen and Hydrogen.

On RHS we have 1 atom of Nitrogen and 3 atoms of Hydrogen.

so , we'll balance Nitrogen first by placing 2 before Ammonia on RHS .

Now , Nitrogen got balanced but we have now 6 atoms of Hydrogen on RHS which could be balanced by putting 3 before H on LHS .

so , got the balanced equation as follows

$\sf \:{N_2 + 3\:H_2 \: \: ➪ 2\: NH_3}$

Hope this helps you to resolve your problem !!
