chemical dependency

Methane (chemical formula CH4) is one of the simplest hydrocarbons, which literally means “containing hydrogen and carbon.”

Its chemical composition is unknown, but it is nitrogenous, and is believed to be produced by the decomposition of gluten.

It has been obtained for chemical examination, principally from peas and beans, and from the almond and oats.

Of its more strictly chemical effects, the most important is probably that which it produces on the temperature of the soil.

No sooner was the spectroscope invented than astronomers hastened by its aid to explore the chemical constitution of the sun.

It is likely that in the classic days of Greece men began to make simple experiments of a chemical nature.
