Cause and effect of chemical reactions

Factors of chemical reaction Can be caused by several things: A. Happened by burning B. Mixing of substances C. Occurred due to electricity A.     Chemical reactions Occur due to burning For burning without external ignition, see spontaneous combustion. For vehicle engines, see internal combustion engine. Fire generated from combustion fuel Burning 'is a sequence of chemical reactions between a fuel and an oxidant, accompanied by the occasional heat production accompanied by light in the form of a fluorescent or flame. In a complete combustion reaction, a compound reacts with an oxidizing agent, and the product is a compound of each element in the fuel with the oxidizing agent. Example: The standard reaction enthalpy for combustion of methane at 298.15 K and 1 atm is -802 kJ / mol. Another example: A simpler example can be observed in combustion of hydrogen and oxygen, which is a ...

Compare and contrast

Compare and contrast are multi-paragraph compositions that explain ways in which two (or, very occasionally, more) subjects are similar or different. In these article, compare means describing similarities between the subjects. When we are comparing Lithium and Calcium. Lithium Lithium (Li) is a silvery gray metal with an atomic number of three. While being the lightest metal under normal conditions, it is still the most dense. With an atomic number of three, lithium has three protons in the nucleus, but like many other alkalai metals it has only one valence electron. Interesting Lithium Facts: ·          It is the least reactive of the alkalai metals. ·          The nucleus of lithium is fairly unstable. ·          Because of this instability, lithium alone almost never appears in nature. · ...
