Answer 1

Question

Chapter 20, Problem 49SCQ

(a)

Interpretation Introduction

Interpretation: The positive factors and concerns of the technique fracking should be given.

Concept introduction:

Fracking or Hydraulic fracturing: The process is a high pressure technique and it is proved to be an unconventional natural gas technology. Using a high pressurized liquid, cracks are created in the rocks which results in the ejection of natural gas and oil.

(b)

Interpretation Introduction

Interpretation: The use of ethanol as a fuel is whether a wise choice should be explained. The arguments for and against for this has to be listed.

Concept introduction:

Different forms of energy sources: Renewable energy source and Non-renewable energy source.

Renewable energy resources: The resources which occur by natural process and can be recyclable or replaced. They will be much useful to human beings.

Non-renewable energy resources: The resources which are once used and which cannot be available again within a given amount of time. Energy derived from fossil fuel is an example for non-renewable resource.

Water, food and air are the major examples for renewable energy resources. The use of renewable sources contributes less pollution in the atmosphere and this is the reason for their increase use. Ethanol in gasoline is a renewable form of energy.

Gasoline, coal, diesel, fossil fuel, plastic.. are examples for non-renewable energy resources. The major disadvantages of these resources are they are not renewed and cannot be recycled.

(c)

Interpretation Introduction

Interpretation: The development of electric cars and cars using natural gas should be encouraged or not. The advantages and disadvantages to owning this cars has to be explained.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
