Question

Which describes the burning of fossil fuels?
O A. Carbon dioxide is released into the atmosphere.
O B. Combustion causes greenhouse gases to break apart.
O C. It is an endothermic reaction.
O D. Crude oil forms during combustion,

Answer 1

Hi there! Let's tackle this together.

The answer to the question is option A.

When fossil fuels mined from the ground are burned with fire and sometimes crude oil, it releases toxic fumes which cause global warming. The same toxic fumes that come from these fossil fuels come from plastic.

The answer is option A.

Answer 2

The burning of fossil fuels yields carbon dioxide, water, and energy. The process of burning fossil fuels is known as “combustion”. So, option A describes the burning of fossil fuels.

What are fossil fuels?

Fossil fuels are made from decomposing plants and animals. These fuels are found in the earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, Oil, and natural gas are examples of fossil fuels.

What is meant by combustion?

• Combustion is the chemical reaction that releases energy trapped in fossil fuels.
• Combustion is an exothermic reaction, which means that energy is released. Usually, heat and light are released during a combustion reaction.
• During exothermic reactions (like combustion), bonds are broken, which allows the energy trapped in the bonds to be released and do work.

Combustion(burning) of fossil fuels:

• During the combustion of fossil fuels, the carbon compound in the fossil fuel reacts with oxygen in the presence of a heat source to form carbon dioxide (CO2) and water.
• Energy is also needed for the fossil fuel to react with oxygen, so the energy use portion of combustion is an endothermic reaction.

Therefore, the burning of fossil fuels releases heat energy, and the primary byproduct of combustion is carbon dioxide (CO2).
