Explain why hydrocarbons are present in so many different compounds.

Hydrocarbons are organic molecules because they are composed of carbon atoms. Why can carbon form so many different types of compounds? The carbon atom is one of the few that will combine with itself. That means it can form long chains and rings onto which other atoms can be attached.

Many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. We use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
