Chapter 10, Problem 69E

Interpretation Introduction

(a)

Interpretation:

The terms ideal, actual, and percentage yield are to be distinguished in the scientific terms.

Concept introduction:

The conversion of the reactants to the products is called a reaction. The amount of product obtained from a reaction is known as yield. The extent of conversion of reactant to the product introduces the terms ideal and percentage yield.

Interpretation Introduction

(b)

Interpretation:

The terms limiting reactant, excess reactant are to be distinguished in the scientific terms.

Concept introduction:

The chemical equation of a reaction represents the stoichiometry with which the reactants are reacting with each other and stoichiometry of the product obtained with respect to that reaction.

Interpretation Introduction

(c)

Interpretation:

The terms heat of reaction, enthalpy of reaction are to be distinguished in the scientific terms.

Concept introduction:

The heat absorbed or given off from a reaction is known enthalpy of reaction. If the heat is absorbed than the enthalpy of reaction is taken a positive value. If the heat is given away then the enthalpy of reaction is taken as a negative value.

Interpretation Introduction

(d)

Interpretation:

The terms chemical equation, thermochemical equation are to be distinguished in the scientific terms.

Concept introduction:

The chemical equation is the representation of the chemical reaction in the equation form. In the chemical equation, the reactants and products of the reaction are placed in the equation with their states mentioned in the brackets.

Interpretation Introduction

(e)

Interpretation:

The terms stoichiometry and thermochemical stoichiometry are to be distinguished in the scientific terms.

Concept introduction:

Stoichiometry is one of the very important parts of chemical equation problems. The stoichiometric ratio of the reactant and products is very useful in chemical equation problem-solving.

Interpretation Introduction

(f)

Interpretation:

The terms joule and calorie are to be distinguished in the scientific terms.

Concept introduction:

One calorie is defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. A calorie is one of the units of energy just like joule. Joule is the SI unit of energy. The relation between a calorie and joule is $\text{1 calorie}=\text{4}\text{.184 Joules}$.
