2. The following reaction is an example of:
\(4NH_3(g) + 5O_2(g) \to 4NO(g) + 6H_2O(g)\)
(i) displacement reaction
(ii) combination reaction
(iii) redox reaction
(iv) neutralisation reaction
(i) and (iv)
(ii) and (iii)
(i) and (iii)
(iii) and (iv)
Ammonia reacts with oxygen to form nitric oxide and water. This is a combination and also a redox reaction.
