Chapter 9, Problem 9.74CQ

Interpretation Introduction

(a)

Interpretation:

Moles of Cl₂ needed to react with 4.50 mol of Al should be determined.

Concept Introduction:

A balance chemical equation provides information about number of moles of products and reactants with the help of mole concept. The actual yield of the product is the amount of product which is formed at the end of reaction experimentally whereas theoretical yield represents the amount of product calculated by expecting that 100 % of reactant changes to product. The percent yield can be shown as:

  $\text{Percent yield = }\frac{\text{Actual yield}}{\text{Theoretical yield}}\times \text{ 100}$

Interpretation Introduction

(b)

Interpretation:

The mass of AlCl₃ produced when 50.2 g of Al reacts should be determined.

Concept Introduction:

A balance chemical equation provides information about number of moles of products and reactants with the help of mole concept. The actual yield of the product is the amount of product which is formed at the end of reaction experimentally whereas theoretical yield represents the amount of product calculated by expecting that 100 % of reactant changes to product. The percent yield can be shown as:

  $\text{Percent yield = }\frac{\text{Actual yield}}{\text{Theoretical yield}}\text{ x 100}$

Interpretation Introduction

(c)

Interpretation:

The mass of AlCl₃ formed when 13.5 g of Al reacts with 8.00 g of Cl₂ should be determined.

Concept Introduction:
