Production of cathode rays - In 1885, Sir William Crookes carried out a series of investigations into the behaviour of metals heated in a vacuum. The experiment of Crookes and others showed that a heated cathode produced a stream of radiation, which could cause gases at low pressure to gl..

Cyclic Electron Transport System - Cylic reaction transport occurs only occasionally when synthesis of carbohydrate is curtailed due to limited supply of CO 2 and NADPH 2 starts accumulating. At this time, there would be no need for additional NADPH 2 . Moreover, the cyclic electronh..

(complex II). The reduced ubquinone called ubquinol is then oxidised with the transfer of electrons to cytochrome c, (complex III) eytochrome c is a small protein attached to outer surface of the inner membrane and is the mobile carrier for transfer of electrons between complex ..

In the overall reaction between magnesium and oxygen as electron does not appear either on the reactant-side nor on the product-side, the number of electrons lost by magnesium must be equal to the number of electrons gained by oxygen. In this way the number o..

Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the ato..

In 1885, Sir William Crookes carried out a series of investigations into the behaviour of metals heated in a vacuum. The experiment of Crookes and others showed that a heated cathode produced a stream of radiation, which could cause gases at low pressure to glow and which, make other substances em..

How many electrons flow through the filament of a 120 V, 60 W electric lamp in one second? Given: Electric power is the product of voltage and curren..

Production of anode rays - Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the ato..

The force which holds together the ions, atoms and molecules in a chemical substance is called as chemical bond. It is the same force which makes substances combine with each other in many different ways to give newer products. The combining tendency of atoms to form chemical bonds can be..

Characteristics of Electrolysis - Following are the characteristics of the electrolysis process: 1) Electrolytic reactions involve the gain of electrons at the cathode and loss of electrons at anode. 2) The cathode reaction is a reduction reaction as the cations accept elec..
