Chapter 17, Problem 17.BCP

(a)

Interpretation Introduction

Interpretation:

The amount of oxygen gas a person must breathe every day to react with glucose to produce $\text{2400}\text{Calories}$ has to be calculated.

Concept Introduction:

The stoichiometry of a chemical species involved in a chemical reaction represents the number of chemical species involved in the chemical reaction.  The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product.  The stoichiometry of a chemical species is also represented in a number of moles.

(b)

Interpretation Introduction

Interpretation:

The amount of current used in the body of a human in one day has to be calculated.

Concept Introduction:

During a redox reaction, the amount of electrons transferred is determined by measuring the current flowing in an external electric circuit for a particular period of time.  The electric charge flowing through an electric circuit is calculated by multiplying the current and the time interval.

(c)

Interpretation Introduction

Interpretation:

The electrical potential required for the current flow through the human body in a day to produce $\text{2400}\text{Calories}$ has to be calculated.

Concept Introduction:

Refer to part (b).
