Acid rain in the form of wet depositions is the most familiar kind to observers. It includes any type of wet, acidic precipitation, like rain, snow, mist, and hail. In regions with a high percentage of rainfall, this is the most common type of acidic deposition, as sulfuric and nitric acid binds with water in the atmosphere before falling to.

Indeed, the reaction of cellulose with sulfuric acid forms an ester C 6 H 8 (SO 4 H) 2 that increases the mass fraction of cellulose. The action of acid on cellulose can also entail the attack of glucosidic bonds by hydronium ions. This induces the failure of the microfibrils and the separation of the fiber constituents.

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal …
Sulphuric acid is used in engine batteries, such as in farming equipment. Large-power batteries work on the basis of the chemical reaction …
Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.It is a trace gas in Earth's atmosphere at 417 …
