Chapter 1.5, Problem 1.10CT

(a)

Interpretation Introduction

Interpretation:

The reason for telling that less energy usage is better should be given and two examples should be provided that demonstrates the connection between using energy and putting waste in the air.

Concept introduction:

Green chemistry: the design of chemical compounds and process that reduce or eliminate the use and generation of hazardous substance, Often referred to as a form of molecular level pollution prevention, Green chemistry relies on a set of 12 principles that can be used to design and re-design molecules, materials and chemical transformation to be safer for human and the environment.

1. 1. It is better to prevent waste than to treat or clean up waste after it is formed.
2. 2. It is better to minimize the amount of materials used in the production of a product.
3. 3. It is better to use and generate substance that is nontoxic

(b)

Interpretation Introduction

Interpretation:

Two examples which demonstrate the reason for making sense that it is better to prevent formation of an air pollutantrather than to try to clean it up once in the air has to be given.
