Chapter 15, Problem 5STP

Interpretation Introduction

Interpretation:

Mole to mole ratio between iron oxide and aluminium oxide needs to be determined.

Concept introduction:

To calculate mole to mole ratio from a chemical equation, firstly the given chemical reaction should be balanced.

From the balanced chemical ratio, mole to mole ratio is calculated using stoichiometric coefficients because stoichiometric coefficients represent the relative molar ratios.

Answer to Problem 5STP

D

Explanation of Solution

$\begin{array}{c}moletomoleratioofFeOandA{l}_2{O}_3=molesofFeO:molesofA{l}_2{O}_3\\ =3:1\end{array}$

Conclusion

The balanced chemical equation directly shows option D is correct and remaining options are wrong.
