Answer 1

4 I₂ + 9 O₂ = 2 I₄O₉

Coefficients:

4 , 9 , 2

hope this helps!

Answer 2

Answer : The coefficients of reactant $I_2$ and $O_2$ are 4 and 9.

The coefficients of product $I_4O_9$ is 2.

Explanation :

The balanced chemical equation will be,

$4I_2+9O_2\rightarrow 2I_4O_9$

By the stoichiometry, 4 moles of $I_2$ react with 9 moles of $O_2$ to give 2 moles of $I_4O_9$.

In the given balanced equation, $I_2$ and $O_2$ are the reactants and $I_4O_9$ is the product.

The coefficients of reactant $I_2$ and $O_2$ are 4 and 9.

The coefficients of product $I_4O_9$ is 2.
