Answer: Coefficient of Fe(III) on the right side of the equation is 2.
Explanation:
The balanced equation for the reactions is as shown below:
\(2Fe(III)+3B{ r }_{ 2 }\longrightarrow 2FeB{ r }_{ 3 }\)
In the equation 2 molecules of Fe(III) react with 3 molecules of \(B{ r }_{ 2 }\) to give two molecules \(FeB{ r }_{ 3 }\). these ratios are also known as molar ratios and are written as coefficients in the equation.
