The concept of limits leads to define and describe continuity and derivative of the function. The continuity of a function has practical as well as theoretical importance. We plot graphs by taking the values generated in the laboratory or collected in the field. We connect..

Indicators are the chemicals that when added to solutions show whether the solution is acidic or basic, by a sudden change of their colour. The common indicators used and the colour changes observed are mentioned belo..

The development of chemistry is based upon the systematic approach of the scientists in carrying out different experiments. Scientific theories, inferences and generalizations are made on the observations recorded. The quantitative information involves the measurement of one or more quantities. The..

The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation giving the distribution of molecules in diffe..

It has been seen that energy change occurring during the reaction at constant temperature and constant volume is given by internal energy change. However, most of the reactions in the laboratory are carried out in open beakers or test tubes, etc. In such cases, the reacting system is open..

Destructive Distillation of Coal - When coal is heated without air, it does not burn but produces many by-products. This process of heating coal in the absence of air is called destructive distillation of coal. The main by products are: coke coal tar amino acid liquor coal gas The destructive disti..

Enthalpy (H) and Enthalpy Change ( D H) - It has been seen that energy change occurring during the reaction at constant temperature and constant volume is given by internal energy change. However, most of the reactions in the laboratory are carried out in open beakers or test tubes, etc. ..
