Which of the following statements is true?

  1. (a) Fuel cells are widely used in automobiles.
  2. (b) H2 is readily available as a transportation fuel.
  3. (c) Petroleum is a mixture of hydrocarbons.
  4. (d) Methane hydrate can never be developed as a commercial energy resource.

Interpretation Introduction

Interpretation: It should be determined for the following fuel provides the greatest amount of energy per gram.

Concept Introduction:

A fuel having higher calorific values is considered to be a good fuel.

Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels.

So the Hydrogen as is considers be an extremely good fuel.

But however, hydrogen gas is not used as a fuel in homes and industries.

Explanation of Solution

Reason for correct option

Crude oil is a mixture of various hydrocarbon and can be physically separated by a distilling process.

Fractional distillation is the use of heat to separate misture .

In the case of crude oil the hydrocarbon at the bottom of the functional column have higher boiling point thant hydrocarbon at the top.

Petroleum is a mixture of Hydrocarbons is explained briefly.

Chemical that occour in TPH include hexane, benzene, tolune, xylene, naphthalene and fluorine, other constituent of gasoline of jet fuels of mineral oils and of other petroleum products.

Petroleum ranges are monitored at various levels depending on the state and testing site...
