Chapter 3, Problem 3.37P
Interpretation Introduction

(a)

Interpretation:

The annual release of all three species of gases due to biomass combustion and the average molecular weight of gases should be calculated.

Concept introduction:

The total gas released will be equal to the sum of amount of gases released. The amount of gas can be calculated in terms of number of moles as follows:

n=mM

For mass the above equation can be rearranged as follows:

m=n×M

Here, n is number of moles, m is mass and M is molar mass.

Interpretation Introduction

(b)

Interpretation:

The environmental hazards associated with CO and CO2 release and other environmental associated with biomass combustion should be listed.

Concept introduction:

Carbon dioxide and carbon monoxide are dangerous to inhale thus, they are considered as air pollutants. They contribute to global warming as they are greenhouse gases.

Interpretation Introduction

(c)

Interpretation:

The percentage change in total CO2 emission since 1990 should be calculated.

Concept introduction:

The total gas released will be equal to the sum of amount of gases released. The amount of gas can be calculated in terms of number of moles as follows:

n=mM

For mass the above equation can be rearranged as follows:

m=n×M

Here, n is number of moles, m is mass and M is molar mass.
