Which one of the following is not the characteristic of Planck's quantum theory of radiation: (1)The energy is not absorbed or emitted in whole number or multiple of quantum
K c is the equilibrium constants when the concentrations are expressed in moles/litre K c = Product of concentrate ions of products / product of concentrate ions of reactants
rules for naming organic compunds
No, it does not depend upon concentrations of reactants, From the Arrhenius equation, k = Ae^(-Ea/RT) We can say, that it is dependent on activation energy(Ea) and temperatu
Soaps and detergents Sodium and pottasium salts of fatty acids such as palmitic acid, stearic acid, oleic acid etc are called soaps, while detergents are ammonium or sulphonate
Formic acid is a weak acid along with a pKa of 3.75. The name comes by the Latin term "formica" ("ant") since this is very plentiful into the secretions of several species of ants,
