Ammonia and oxygen combine to produce water vapour and nitric oxide as per the chemical equation: `4NH_(3)(g) + 5O_(2)(g) to 6H_(2)O(g) + 4NO`.
(ii) How many moles of oxygen are required to burn 85 g of ammonia?

Answer

1

Explanation

`underset(4 mol )underset("4 volumes ")(4NH_(3)(g)) + underset(" 5mol")underset(" 5 volumes")(5O_(2)(g)) to underset("6 mol ")underset(" 6 volumes")(6H_(2)O(g)) + underset("4 mol ")underset("4 volumes")(4NO(g)) `
