Answer 1

Answer:

• An acid is a molecule or ion capable of either donating a proton, known as a Brønsted–Lowry acid, or, capable of forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids

• Acid gas is a particular typology of natural gas or any other gas mixture containing significant quantities of hydrogen sulfide, carbon dioxide, or similar acidic gases. The term/s acid gas and sour gas are often incorrectly treated as synonyms.

• Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5-8.5, but acid rain has a pH level lower than this and ranges from 4-5 on average.

Answer 2

what is acid ?

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

what is acid gas ?

Acid gas is a particular typology of natural gas or any other gas mixture containing significant quantities of hydrogen sulfide, carbon dioxide, or similar acidic gases. The term/s acid gas and sour gas are often incorrectly treated as synonyms.

what is acid rain?

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
