Answer 1

The answer is .

3N2 +9H, → 6NH

EXPLANATION -

The left hand diagram shows the reactants, and the right hand diagram shows the products.

We can see the reactants are N₂ and H₂, whereas the product is NH₃.

Counting the molecules,

Number of N₂ molecules = 3

Number of H₂ molecules = 9

Number of NH₃ molecules = 6

i.e. 3 N₂ molecules react with 9 H₂ molecules to give 6 NH₃ molecules.

So the reaction will be

3N2 +9H, → 6NH

As we can see, the reactants are written on the left side of the arrow, and products are written on the left side of the arrow. The arrow is pointed towards the products.

3,6 and 9 are known as the stoichiometric coefficients of N₂, H₂ and NH₃ respectively.

Now, 3, 6 and 9, all are divisible by 3. So we can divide the whole equation by 3 to get a simplified equation.

The simplified equation will be .

N2 + 3H2 + 2NH2
