addition problems

If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..

Reactions in which two molecules react to form a single product are called addition reactions. For example, Depending upon the type of attacking reagent, the substitution or addition reactions are also classified as free radical, electrophilic or nucleophilic substitution o..

Benzene gives some addition reactions. Some typical reactions ar..

When the molecules of same monomer or different monomers simply add together to form a polymer,the process is called addition polymerization. The monomers commonly used are unsaturated compounds such as alkenes, alkadienes and their derivatives. This mode of polymerization can take place ..

Addition polymers are formed when monomer units are separately added to form long chains without elimination of any by-product molecules. These polymers are formed by reactions between monomer molecules possessing multiple bonds. Example: Ethylene undergoes polymerization to form polythe..

Benzene on reduction with hydrogen under pressure in the presence of finely divided nickel at 200C, gives an addition product hexahydrobenzene (cyclohexane)...

Lower alkenes are mixed with air and passed under pressure over a silver catalyst at 200-400°C. This gives epoxides by adding one atom of oxygen across the double bond. The epoxides so obtained are used in detergents. ethene ..

Addition of Matrices - To add two matrices: (i) Check whether they are of the same order. (ii) If they are of the same order, add the corresponding elements. (ii) It will be seen that the matrix obtained after addition will also be a matrix of the same order. If and then If and ..

Electrolysis (Additional) - Chemical energy can be converted into electrical energy with the help of a galvanic cell. Conversely, the phenomenon of chemical changes taking place by the passage of electricity through an electrolyte is called electrolysis. Humphrey Davy (1807) showed this i..

1) An insecticide from neem Azadrachta indica has been developed in the USA as a dust and spray. 2) A safe herbal pesticide has been developed from garlic and chillies in pune -maharashtra. 3) Scientists at CDRI in lucknow have developed biocide from the micro-organism Bacillus sphacricus which ha..
