What type of coal contains the least amount of carbon?lignitebituminousanthracitepeat

The type of coal that contains the least amount of carbon is peat. Here's the step by step explanation:

1. Peat: This is not actually a type of coal, but it's the material that coal forms from. It's an accumulation of decayed vegetation or organic matter that can eventually turn into coal after millions of years. Peat contains the least amount of carbon among the options provided.

2. Lignite: This is the lowest rank of coal, often referred to as brown coal. It's used almost exclusively as fuel for steam-electric power generation. It contains slightly more carbon than peat.

3. Bituminous: This is the most common type of coal found in the United States. It has a higher carbon content than lignite, but it's less efficient than anthracite.

4. Anthracite: This is the highest rank of coal and contains the most carbon. It's harder, more efficient, and burns cleaner than other types of coal.
