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

(A) 2H 2 (l) + O 2 (l) → 2H 2 O(g)

(B) 2H 2 (g) + O 2 (l) → 2H 2 O(l)

(C) 2H 2 (g) + O 2 (g) → 2H 2 O(l)

(D) 2H 2 (g) + O 2 (g) → 2H 2 O(g)

 

Answer

2H 2 (g) + O 2 (g) → 2H 2 O(l)

Here,

  • Both hydrogen and oxygen are gases and they combine to form water which is liquid.

 

So, the correct answer is (c)
