Answer:
The balanced chemical equation is given as:
Explanation:
During the balancing of the chemical reaction, balance all the atoms of every atoms except oxygen element.
There are 2 nitrogen atoms on both sides. Nitrogen atom is balanced.
There are 4 hydrogen atoms on left side and 2 hydrogen atom on right side.Write 2 in front of to balance the hydrogen atoms.
Now ,see the number of oxygen atoms on both sides. Here on both sides oxygen atoms oxygen atom are same.
So, write 2 in front of , 2 in front of and 4 in front of .
All the atoms of all each and every element is balanced in the chemical equation.
