What is the coefficient for hydrogen in the balanced equation for the reaction of solid molybdenum (iv) oxide with gaseous hydrogen to form solid molybdenum and liquid water?

The coefficient for hydrogen in the balanced equation of solid molybdenum (iV) oxide with gaseous hydrogen is 2

Explanation

Coefficient is defined to as a number in front of a chemical formula in a balanced chemical equation.

The reaction of molybdenum (iv) oxide with gaseous hydrogen is as below,

MoO2 + 2 H2→ Mo + 2 H2O

From balanced equation above the coefficient for H2 is 2 since the number in front of H2 is 2
