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)(c) 2H2(g) + O2(g) → 2H2O(l)(d) 2H2(g) + O2(g) → 2H2O(g)

Answer»

The correct option is (c) 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.
