nitric acid can be made using ammonia.
a) the first stage in the manufacture of nitric acid is to oxidise ammonia, nh,,
to nitrogen(ii) oxide, no. balance the equation for the reaction.
nh, + o, → no + h, o

4NH3 + 5 O2  →  4 NO  + 6 H2O

Explanation:

The formula of ammonia is NH3. Oxidise  means adding 02. This will result in Nitrogen(II)oxide which is NO, and H20.

On the left side we have 3xH and on the right side we have 2x H. To get the same amount we multiply the left side bij 2 and the right side by 3.

This gives us 2N on the left side, so we multiply NO by 2, to get the same amount of N.

This gives us 5x O at the right side, so to get the same amount we multiply O2 by 5/2 ( we already got 2x O).

This gives us 2NH3 + 5/2 O2  → 2NO + 3H20

We multiply by 2 to get rid of fractions, which will give us:

4NH3  + 5 O2  → 4NO + 6H20
