Yes, coal is composed from the element carbon.
No, coal and diamond are not the same chemical material. Coal is primarily composed of carbon, while diamond is a pure form of carbon with a different crystal structure that gives it its unique properties, such as extreme hardness and brilliance.
Carbon in coal is oxidized to form carbon dioxide when coal undergoes combustion.
No, coal is not a carbon sink. In fact, burning coal releases carbon dioxide into the atmosphere, contributing to climate change.
Your question isn't rigorous enough. When you burn coal you are combining carbon from the coal with oxygen in the air. So the mass of Carbon Dioxide created is greater than the original mass of coal. There is no mass destroyed however, you just have to be more rigorous in the parameters of your question.
The main element in coal is carbon.
no they are not the same although commercial coal is made up of at least 70 % of carbon
Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.
Carbon, hydrogen, oxygen, nitrogen, and sulfur. The same as in your own proteins - except for the excess of carbon.

coal is made out of carbon because u need carbon to make coal
Carbon in coal is oxidized to form carbon dioxide when coal undergoes combustion.
coal is mainly carbon....
No, coal is not a carbon sink. In fact, burning coal releases carbon dioxide into the atmosphere, contributing to climate change.
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
No. But burning coal will likely produce carbon monoxide.
Coal is not all the same. Different coals have different amounts of carbon, Bituminous, or soft coals have the highest percentage of carbon, up to almost 90%, Anthracite or hard coals have close to 80% carbon content, and lignite, brown coals have about 40% carbon content. Carbon content is what determines how much CO2 is produced by coal's combustion.
