Chapter 11, Problem 52A

Interpretation Introduction

Interpretation:

The coefficient in balanced chemical equation needs to be determined.

Concept introduction:

Balanced chemical equation show number of particle or moles of reactant which is equal to number of moles or particles of product.

Answer to Problem 52A

Coefficient of W, X, Y and Z are $3,1,2\&4$ respectively.

Explanation of Solution

From the given table, the least common number of moles is $0.30$. Thus, coefficient can be find by whole number least number which calculated by divide $0.30$ from each quantity.

So,

$W=\frac{0.90}{0.30}=3,X=\frac{0.30}{0.30}=1$

$Y=\frac{0.60}{0.30}=2,Z=\frac{1.20}{0.30}=4$

$3W+X\underset{}{\overset{}{\to }}2Y+4Z$

Conclusion

Coefficient is related to least whole number mole ratio.
