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)
