Question

17. In which of the following chemical equations, the abbreviations
represent the correct states of the reactants and products involved
at reaction temperature?
(a) 2H (1) + 0,(1) ► 2H 0(g)
(b) 2H,g+ O2(1)→ 2H,O(1)
(c) 2H (g) + O2(g) → 2H,O(1)
(d) 2H,(g) + 0,(g) → 2H,O(g)​

Answer 1

ANSWER

2H

2 (g)+O

2 (g)⟶2H

2

O(l) is the correction reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.
