Much of its surface area is occupied by the Telangana Plateau in the north and the Golconda Plateau in the south and is composed of gneissic rock (gneiss being a foliated rock formed within Earth’s interior under conditions … Read more

The Rate of a Chemical Reaction

The Rate of a Chemical Reaction The rate of a chemical reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed … Read more

Mesolithic Period- Food producers

Mesolithic Period- Food producers The period of the earth’s history called the Stone Age was filled with remarkable achievements, made by early humans who roamed the globe following large animals around for food and for clothing. These early nomadic humans called hunter-gatherers needed tools and weapons that would be strong enough to take down animals … Read more

The hymns composed by the Vedic priests had perfected a poetic technique. These hymns were praise of their gods and were sung at sacrifices. These were … Read more

Metals and Non-metals

Metal   In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic Bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of Elements as distinguished by their ionization and bonding properties, along … Read more

The Environment – development debate

Environmental influences are important both at the prenatal and postnatal stages of Human Development. At the prenatal stage, when a fetus is in the mother’s womb,  internal or external harmful agents, such as certain legal or illegal drugs, alcohol, lead and pollutants can harm the unborn baby’s development. The mother’s Nutrition, diseases and emotional Stress … Read more

Chemical kinetics

Chemical kinetics Chemical kinetics is that branch of chemistry which deals with the study of the speeds or the rates of chemical reactions, the factors affecting the rates of the reactions and the mechanism by which the reactions proceed. It concerns itself with the measurement of rates of reactions proceeding under the given conditions of … Read more

Fast And Slow Chemical Reactions

 Slow reactions Chemical reactions that occur very slowly and can take a long time for completion are called slow reactions.  Usually covalent compounds are involved in slow reactions.Some reactions can take days, weeks and months to complete; they are called very slow reactions.For example, Milk may take several hours or a day to convert to curd, while it … Read more

Catalyst

Catalyst Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. ENZYMES are naturally occurring catalysts responsible for many essential biochemical reactions. Most solid catalysts are metals or the oxides, sulfides, and halides of metallic Elements and of the semimetallic elements boron, aluminum, and silicon. Gaseous and liquid catalysts … Read more
