Life has come into being through the connection of elements. Chemical elements are atoms with the same number of protons in the nucleus. The number is called … Chemical Elements
Note about this article This article refers to burns in chemistry. See also under burns (medicine). Burns In chemistry, a combustion usually refers to an oxidation in which heat, light, fire, and energy are released. For example, the alkane octane is an important component of gasoline: C8H18 (octane) + 12.5 O2 (oxygen) 8 CO2 (carbon … Burns (Chemistry)
Definition Alkanes are organic compounds composed exclusively of carbon and hydrogen atoms. They belong to the hydrocarbons and contain only C-C and C-H bonds. Alkanes are not aromatic and saturated. They are referred to as aliphatic compounds. The general formula of acyclic alkanes is C n H 2n+2 . The simplest alkanes are the linear … Alkanes
Definition Alkenes are organic compounds which contain double bonds between carbon atoms (C=C). Alkenes are hydrocarbons, meaning that they consist exclusively of carbon and hydrogen atoms. They are also called unsaturated compounds. This is in contrast to the saturated ones, which contain only single bonds (C-C). Alkenes can be linear (acyclic) or cyclic. Cycloalkenes are, … Alkenes

Structure and properties Sulfur dioxide (SO2, 64.1 g/mol) exists as a colorless gas with a characteristic pungent and irritating sulfur odor that is soluble in water. The boiling point is -10°C. Sulfur dioxide is not combustible and is heavier than air. … Sulfur Dioxide
The air we breathe is a mixture of gases, most of which is nitrogen (75 percent). The oxygen content, on the other hand, is only 21 percent. This amount is sufficient for humans to oxygenate the blood for energy production. Oxygen is essential for life Oxygen is absorbed into the lungs with respiration, and from … Who Discovered the Oxygen?
