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.
