Types of Fossil Fuels Quiz

Recall the three different types of fossil fuels.

• Coal, Oil, Natural Gas

• Solar, Wind, Hydro

• Biomass, Geothermal, Nuclear

• Hydrogen, Ethanol, Methanol

Fossil fuels are described as being non-renewable. What does this mean?

• They can be replenished quickly.

• They are available in unlimited quantities.

• They cannot be replaced once used.

• They are environmentally friendly.

Bioethanol can be produced in organisms through a process known as fermentation. Which of the following is the balanced chemical equation for fermentation?

• C6H12O6 → 2 C2H5OH + 2 CO2

• C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

• C2H5OH + O2 → CO2 + H2O

• C6H12O6 → 2 C2H5OH + 2 H2O

Bioethanol can be produced in organisms through a process known as fermentation. What conditions and other substances are required for the fermentation process to occur effectively?

• Presence of yeast, absence of oxygen, and a suitable temperature

• Presence of bacteria, high oxygen levels, and low temperature

• Presence of fungi, high oxygen levels, and high temperature

• Presence of algae, absence of oxygen, and low temperature

Crude oil can be classified as a biofuel because it originally comes from plants.

• True

• False

Fossil fuels are recognised as a significant contribution to the increase in greenhouse gas emissions. Alternative fuels to fossil fuels as an energy source exist but they are not yet at the stage where they can completely replace them. From different groups, there are concerns about the suitability of biofuels as a replacement for fossil fuels. Define ‘biofuel’.

• A fuel derived directly from living matter.

• A fuel that is mined from the earth.

• A synthetic fuel created in laboratories.

• A type of fossil fuel.

Alternative fuels to fossil fuels as an energy source exist but they are not yet at the stage where they can completely replace them. From different groups, there are concerns about the suitability of biofuels as a replacement for fossil fuels. b. Which of the following is an example of a biofuel?

• Ethanol

• Coal

• Natural Gas

• Petroleum

What is one advantage for society of adding small quantities of biofuels to current fossil fuels used for powering automobiles?

• It reduces greenhouse gas emissions.

• It increases the cost of fuel.

• It decreases engine efficiency.

• It makes fuel less available.

Which of the following is a reason why it is currently unfeasible to incorporate a higher percentage of these biofuels into either petrol or diesel fuels?

• Biofuels are more expensive to produce.

• Biofuels have lower energy content compared to fossil fuels.

• Biofuels can cause engine damage in older vehicles.

• Biofuels are widely available and easy to produce.

Write the simplified balanced chemical equation for photosynthesis.

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• CO2 + H2O -> C6H12O6 + O2

• 6CO2 + 12H2O -> C6H12O6 + 6O2 + 6H2O

• CO2 + H2O -> C6H12O6 + 6O2
