Answer : The balanced chemical reaction will be:
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
As per question, when 2 molecules of hydrogen gas and 1 molecule of oxygen gas react to yield 2 molecules of water.
The balanced chemical reaction will be:
