Answer to Problem 2RQ

Bituminous coal has large percent mass of carbon.

Explanation of Solution

Given pie chart for the Lignite coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  1

Given pie chart for the Bituminous coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  2

In the lignite coal, percent of carbon is 71% and in the bituminous coal, percent of carbon is 80%. So, the coal having large percent mass of carbon is bituminous coal.

(b)

Interpretation Introduction

Interpretation: The type of coal that contains large percent mass of sulphur needs to be determined using the given charts.

Answer to Problem 2RQ

Coal that contains large percent mass of sulphur is bituminous coal.

Explanation of Solution

Given pie chart for the Lignite coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  3

Given pie chart for the Bituminous coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  4

In the lignite coal, percent of sulphur is 1% and in the bituminous coal, percent of carbon is 5%. So, the coal having large percent mass of sulphur is bituminous coal.

(c)

Interpretation Introduction

Interpretation: The element present in equal amounts in both the types of carbon (coal) needs to be determined.

Concept Introduction : The substance produced from dead plants and animal remains which are buried and go through high pressure and heat over a long time period is coal. Coal is a solid fossil fuel consisting of carbon. There are various types of coal, such as, lignite, bituminous etc.

Answer to Problem 2RQ

Nitrogen is present in equal amounts in both the coal.

Explanation of Solution

Given pie chart for the Lignite coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  5

Given pie chart for the Bituminous coal is as follows:

  World of Chemistry, 3rd edition, Chapter 10.4, Problem 2RQ , additional homework tip  6

The percentage of nitrogen in both the coal (lignite and bituminous) is 1%. So, nitrogen is present in equal amount in both the coal.
