Question

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

2H2(l) + O2(l) → 2H2O(g)

2H2(g) + O2(l) → 2H2O(l)

2H2(g) + O2(g) → 2H2O(g)

2H2(g) + O2(g) → 2H2O(l)

​

Answer 1

Answer:

option c..2H2(g)+O2(g)⟶2H2O(l)

Explanation:

2H2(g)+O2(g)⟶2H2O(l) is the correction reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.

Answer 2

Answer:

The 4th statement is correct:

2H2(g) + O2(g) --> 2H2O(l)

hydrogen and oxygen are gases which combine to form water which is a liquid.
