Question

balance N2+O2+H2O=HNO3

Answer 1

The Balanced equation is:-

2N2 + 5O2 + 2H2O => 4HNO3

Hope it helps...^_^

Answer 2

The balanced equation is $\bf 2N_2+5O_2 +2H_2O \rightarrow 4HNO_3$.

We have been given the equation $N_2+O_2 +H_2O \rightarrow HNO_3$

Let the coefficient of $N_2$ be x, $O_2$ be y, $H_2O$ is z, and $HNO_3$ be a.

Hence if we equate the number of Nitrogen atoms, we get

$2x=a$

Hence if we equate the number of Oxygen atoms, we get

$2y+z=3a$

Hence if we equate the number of Hydrogen atoms, we get

$2z=a$

Therefore

$2y+\frac{a}{2} =3a\\\\2y=2.5a$

Let a = 4.

Hence $x=2$, $z=2$, and $y=5$.

Therefore we get the balanced equation $\bf 2N_2+5O_2 +2H_2O \rightarrow 4HNO_3$.
