They are used as insecticides, acaricides or nematicides to kill insects, mites and nematodes respectively. They can kill many aerobic and anaerobic bacteria in soil. They are easily escaped in underground water- when excess dosage is used. Examples: Carbofuran, aldicarb and carbor..

Carbon undergoes oxidation by combining with oxygen at higher temperature to form to oxides, viz., carbon monoxide (CO) and carbon dioxide (CO 2 ). Carbon monoxide is formed, when incomplete combustion of carbon or carbon contai..

Adding (i) and (ii), we get..

Electronic configuration is 2,4. It needs four more electrons to complete its octe..

Carbon forms the largest number of compounds, next only to hydrogen. It ranks seventeenth in the order of abundance in the earth's crust. Carbon occurs in the free native state as well as in the combined state. Carbon and its compounds are widely distributed in nature...

During photosynthesis, hydrogen of water is used to fix carbon dioxide and its oxygen is released. Water is obtained through the root hairs by absorptio..

Water is an essential factor in photosynthesis. The effect of water can be understood by studying the yield of crops which is the direct result of photosynthetic activity. It is found that even slight deficiency of water results in significant reduction in the crop yi..

When ammonia is treated with a mixture of carbon dioxide and water vapour, it combines to form ammonium carbonate, a colourless, crystalline, highly sublimable salt...

The two atoms of oxygen mutually share two pairs of electrons each with an atom of carbon to form a molecule of carbon dioxide (Fig. 3.13). Note : In the above diagram only the valence or outermost shell of carbon and oxygen atoms are shown..
