Question

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

(a) 2H2(l) + O2(l) → 2H2O(g)

(b) 2H2(g) + O2(l) → 2H2O(l)

2H2(g) + O2(g) → 2H2O(l)

2H2(g) + O2(g) → 2H2O(g)​

Answer 1

Option 4th is correct because 2H20 is a gas

Answer 2

Answer:

Answer: 2H2(g) + O2(g) → 2H2O(l)

During the formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.
