 Acid An acid is a substance which forms H+ ions as the only positive ion in aqueous solution. Examples:- Hydrochloric acid dissolved in water forms H+ and Cl– ions   HCl —> H+ + Cl–   Sulphuric acid dissolved in water forms H+ and SO42- ions   H2SO4 —>2H+ + SO42-   Nitric acid forms H+ and NO3– ions when dissolved in water … Read more Acids And Bases

 Electric transformers Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about … Read more Electric Transformers

 Determinants of Nuclear Tests: Pokhran I (1974) and Pokhran II (1998) Pokhran 1 test The emergence of China as fifth nuclear power in October 1964 constituted a significant threat to India’s territorial integrity and sovereignty. The strained relations between the two countries after the 1962 aggression sparked off an acrimonious debate on defence … Read more Determinants Of Nuclear Tests

 Bio-fuel cultivation and extraction Biofuel is a type of fuel whose energy is derived from biological carbon fixation. Bio‐ fuels include fuels derived from biomass conversion, as well as solid biomass, liquid fuels and various biogases. Although fossil fuels have their origin in ancient carbon fixation, they are not considered biofuels by the … Read more Bio Fuel Cultivation And Extraction

 Synthetic fibers (nylon and rayon),, polystyrene Synthetic fibers are made from raw materials such as petroleum, based on chemicals or petrochemicals. These materials are polymerized into a long, linear chemical with different chemical compounds and are used to produce various types of fibers. Synthetic fibers account for about half of all fiber usage, … Read more Synthetic Fibers
