Sulfur dioxide


Made from: Sulfur, Oxygen


Symbol: SO₂


Chemical Bonding: Covalent bonding


Harmful effects:- It contributes to respiratory illness and aggravates existing heart and lung diseases.
                              -it contributes to the formation of acid rain, which: 

                                -   damages trees, crops.

                                -makes soils, lakes, and streams acidic.                             -it contributes to the formation of atmospheric particles that cause visibility impairment, most noticeably in national parks.

Constituent elements of Sulfur dioxide:

Sulfur

Sulfur is the chemical element that has the atomic number 16. It is denoted with the symbol S. It is an abundant, multivalent non-metal. Sulfur, in its native form, is a bright yellow crystalline solid. In nature, it can be found as the pure element and as sulfide and sulfate minerals. It is an essential element for life and is found in two amino acids: cysteine and methionine. Its commercial uses are primarily in fertilizers, but it is also widely used in black gunpowder , matches , insecticides and fungicides. Elemental sulfur crystals are commonly sought after by mineral collectors for their brightly colored polyhedron shapes.

Oxygen

Oxygen is a colorless, odorless, tasteless gaseous chemical element which appears in great abundance on Earth,  trapped by the atmosphere. It is a vital component of the respiration process; without oxygen,  most organisms will die within minutes. A number of forms of oxygen and oxygen compounds  can be found in nature.  Oxygen can also be isolated and sold in pure form for an assortment of uses,  and was first isolated and identified in 1774. he atomic number of oxygen is eight,  and it is identified by an O symbol on the periodic table of elements.  In addition to being very widely distributed on Earth,  oxygen is also the third most abundant element in the universe, and it is a key catalyst in many chemical reactions.  Oxidation is one such reaction, and it occurs when oxygen mixes with other elements and compounds.  Oxygen also plays a role in combustion. Formation Sulfur dioxide is formed when sulfur containing compounds are burned (oxidized). Sulfur dioxide is a by-product of other processes in industry. Industries then release the gas into the atmosphere. The clean air act has forced industry to clean the smokestack smoke with scrubbers which remove some of the sulfur dioxide. As you know, sulfur dioxide, when combined with water in the clouds forms sulfuric acid one kind of acid rain. DOT AND CROSS DIAGRAM
