-Is a mixture of large molecules made from carbon, hydrogen, sulfur and other elements 
-More than 50% of its weight is carbon]]> 2017-02-01 10:17:10 UTC https://padlet.com/cinnamonlane1/iu1vvx98zxee/wish/150779467 Combustion Equation https://padlet.com/cinnamonlane1/iu1vvx98zxee/wish/150782213 C+O2------>CO2]]> 2017-02-01 10:30:34 UTC https://padlet.com/cinnamonlane1/iu1vvx98zxee/wish/150782213 How is coal obtained and what are the environmental impacts? https://padlet.com/cinnamonlane1/iu1vvx98zxee/wish/150794851 Coal is found underground, in seams. A seam is a layer containing coal thick enough to be profitably mined. It can be obtained by surface mining (including strip mining), removing the soil and rock above the coal seam to be removed from the surface. In addition, the use of underground mining involves digging shafts deep into the earth to access seams further beneath the earth.
Strip mining eliminates existing vegetation, displacing and destroying wildlife and habitat as a result of the construction of haul roads, stockpiling of topsoil, and the hauling of soil and coal. This increases the quantity of dust around mining operations. Dust degrades air quality and detrimentally impacts the health of mine workers. At times, tops are removed from mountains or hills. The soil and rock removed is deposited in nearby valleys, hollows and depressions, resulting in blocked, contaminated waterways containing poisonous substances such as arsenic and mercury. Some of these waterways are used by people for fishing and transport, thus this pollution also impacts their way of life.

-Coal burning produces harmful by-products like nitrogen, carbon dioxide and sulfur dioxide
-Coal burning can cause pollution to the environment like acid rain
-Coal energy is a non-renewable source, meaning coal will eventually run out
-Underground mining is very hazardous because cave-ins and explosions are common
-Methane is also released into atmosphere

-Easy to burn
- Inexpensive to buy on open market due to large reserves and easy access ability 
- Coal is the least expensive fossil fuel because it is rather simple to mine
- It's easily transported to many areas in the world
-Produces high energy upon its combustion process

Are there more efficient and sustainable ways to use coals, which will allow for the carbon dioxide to  be utilised more effectively as well?
