H2 + O2 => _____(a) H2O(b) OH(c) H3O(d) 2H2OI have been asked this question by my college professor while I was bunking the class.Query is from Combustion of Fuels topic in section Steam Power Plant of Energy Engineering

Answer»

Right choice is (d) 2H2O

To explain I would say: Based on molecular WEIGHT, 32kg of sulfur combines with 32kg of oxygen forming 36KG of water.

Balanced equation: 2H2 + O2 => 2H2O

4kg of H2 + 32kg of O2 => 36kg of H2O

1kg of H2 + 8KG of O2 => 9kg of H2O.
