Describe how coal, oil, and natural gas form, how these fuels are used, and how using each fuel affects the environment.​

Coal forms from the remains of plants that live in swamps for millions of years while oils and natural gases are formed from the decay of tiny marine organisms that have accumulated on the bottom of the ocean. The use of each fuel affects the environment by the cause air pollution.

The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom.

Explanation:

Hydrogen in a bond still only has one electron, while it takes two electrons for a stable electron pair. Any compound with polar covalent bonds has the potential to form hydrogen bonds.
