Q.
In which of the following chemical equations, the abbreviations represent the correct states of the reactants and products involved at reaction temperature

1 $2 H_{2} (I) + O_{2} (I) \to 2 H_{2} O (g)$

2 $2 H_{2} (I) + O_{2} (I) \to 2 H_{2} O (I)$

3 $2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (I)$

4 $2 H_{2} (g) + O_{2} (g) \to 2 H_{2} O (g)$

Ans.
(3)

Hydrogen and oxygen occur in the gaseous state in nature, whereas when they combine to form water, the physical state of the matter converts to the liquid state.
