methane reacts with limestone

What Are the Uses of Methane?

Methane is utilized as fuel and in chemical reactions to produce commercially used chemicals such as carbon tetrachloride, carbon black and as a source of hydrogen. Methane reacts at high temperatures with steam to yield the hydrogen used in the manufacturing of explosives and ammonia-based fertilizers.Read more≫

How Is Limestone Made?

Limestone can be formed as a result of evaporation, as is the case for stalactites and stalagmites in caves, or through the accumulation of calcium carbonate in marine environments. Limestone is either a biological or a chemical sedimentary rock, depending on its method of formation.Read more≫

From What Is Limestone Made?

Limestone is a sedimentary rock that is at least 50 percent calcium carbonate, and is found in nature in the form of the mineral calcite. Calcium carbonate has the molecular formula CaCO3. The formation of limestone can occur either through evaporation or the accumulation of shells from dead organisms like oysters in a marine environment.Read more≫
