Hydrocarbons are compounds that are made up of atoms of carbon and hydrogen exclusively. The unique nature of the carbon ensures that it shares a strong covalent bond with hydrogen. Since carbon atoms will make long chains with relative ease, hydrocarbons can be very big molecules linking even hundreds of atoms. Examples of hydrocarbons include … Read more

What Are Polarized Light? A light wave is an electromagnetic wave that travels through the vacuum of outer space. Light waves are produced by vibrating electric charges. More importantly, light waves are transverse, that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. Polarized light waves are light … Read more

Polar Covalent Bonds Polar covalent bonding is a type of chemical bonding where a pair of electrons is unequally shared between two atoms. In other words, the distribution of electrons around the molecule is no longer balanced. This is due to one of the elements having a higher electronegativity than the other.  Atoms with high … Read more

Surveying is generally described as methodology of making scientific measurements on or above the surface of earth with the objective of determining points so as to produce a plan or map. Surveying is used widely in almost all civil engineering projects such as construction of building, bridges, reservoirs, dams, railways, roads, irrigation projects etc. Primarily, … Read more

What Is Molecule? A molecule can be described as two or more atoms of the same or different element that are bound together by chemical bonds. Each atom carries a certain number of electrons that orbit around nucleus. A molecule may be homonuclear, which means, it consist of atoms of one chemical element as with … Read more

What Is Nitrification? In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of Ammonia with the help of Nitrosomonas bacterium species. Later, the produced nitrites are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants. … Read more

What Is An Element? An element is a pure substance that cannot be decomposed into simpler substances by ordinary chemical processes. Although elements cannot be changed by chemical reactions, new elements may be formed by nuclear reactions. Elements are defined by the number of protons they posses. Atoms of an element all have the same … Read more

Grasshopper The grasshopper is a medium to large sized insect and common in greatest numbers in lowland tropical forests, semiarid regions and grasslands. They are best known for their ability to jump incredible heights and distances. Like all insects, all species of grasshopper have a three-part body that is, head, thorax and the abdomen. They … Read more

Plasmodium vivax  Plasmodium vivax is a protozoalparasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring malaria. Although it is less virulent than Plasmodium falciparum, the deadliest of the five human malaria parasites, P. vivax malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen). P. vivax is carried by the female Anopheles mosquito. P. vivax are … Read more

What Is Plasticizer? Any substance added to a polymer material that can increase the plasticity of a polymer is referred to as a plasticizer. Plasticizers make plastics elastic, extensible, flexible and plastic at low temperatures. Plasticizers are produced by reaction of an alcohol with an acid such as adipic acid, phthalic anhydride and so forth. … Read more
