Do the balances of gases in the air are changed when coal is burned?

Yes. You get slightly more carbon dioxide and less oxygen. However, you wont notice unless you burn lots and lots of coal in a small space. When the oxygen starts to run out, you get carbon monoxide (the one that kills you). In real life, you're more likely to notice the soot, smoke and water vapour given off to the air, but strictly speaking these aren't gases.

How can science help people save resources such as coal?
Electricity production is the main use for coal around the world. Saving electricity means less coal will need to be mined, shipped and burned.
What is the disadvantage of using coal to generate electricity?
There are several disadvantages to using coal to generate electricity. When coal is burned, it releases lots of carbon dioxide, which is a problem because the atmosphere already has too much carbon dioxide and it is causing global warming. In addition, there are impurities in coal which result in other forms of air pollution, particularly sulfur dioxide which results in acid rain. Coal mining is also a dangerous activity that results in many deaths. And although there is a lot of coal, it is still not a renewable resource, and it will eventually run out, if we continue to burn it.
What are the disadvantages of using coal as a fuel?
Coal is used in many power plants to produce electricity. Mining coal requires stripping away thick layers of soil and rock, destroying ecosystems. Layers of soil and rock take billions of years to form. These fuels have to be burned to release the energy stored inside them. The burning of fossil fuels produces waste gases that causes air pollution, including smog and acid rain. Because coal contains carbon it releases carbon dioxide when it is burnt. Carbon dioxide is the pollution that is causing global warming. It can be very dangerous to mine it. Takes thousands of years to form (is running out) Produces sulphur dioxide when burnt (sulphur dioxide > acid rain) Also it causes smog and releases methane
What are 4 uses of coal?
1)It is burned for electricity 2)It is manufactured into things such as medicine, dyes, and plastic. 3)Is used in the production of ethonal 4)Can produce syngas which which can be converted into gas or diesel for a vehicle.
What happens to the coal after it is burned?
When coal is burned it releases bad gases into the atmosphere which creates pollution.
Which greenhouse gases are added to the atmosphere when coal oil and natural gas are burned?
Carbon dioxide is added to the atmosphere;here when coal oil and natural gas are burned?
How do power plants release the energy in coal?
They burn it. It's the heat and expanding gases from the coal being burned which provides the energy.
How have human activities changed the greenhouse gases?
Human activities like burning fossil fuels (coal, oil and natural gas) and deforestation have increasedlevels of greenhouse gases.
Which coal is burned with the least flame?
anthracite coal
