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
The coefficient is the constant number that is placed before the balanced chemical of the reaction. The coefficient of hydrogen in the reaction is 2.
A Coefficient is a specific number that is written before the balanced atom of a reaction. They are used to write the balanced chemical reactions.
The reaction of solid molybdenum (iv) oxide with gaseous hydrogen can be shown as:
[tex]\rm MoO_{2} + 2 H_{2} \rightarrow Mo +2 H_{2}O[/tex]
Hydrogen reacts with molybdenum (iv) oxide to form solid molybdenum and liquid water.
From the balanced chemical reaction, it can be seen that 2 is the coefficient of the hydrogen atom.
Therefore, 2 is the coefficient of hydrogen.
