nitrates and their properties

1) Ammonium Nitrate is a colourless crystalline solid. 2) It is highly soluble in water. Its solubility in water is 242 g at 30 o C. 3) When heated, it melts and then decomposes to give nitrous oxide and water. It explodes when heated...

Nitric acid is a strong acid. In moderately dilute solution (~ 0.1 M) it is dissociated to an extent of about 93%, in accordance with the reaction, It decomposes carbonates and bicarbonates as:..

Chemical Properties of Sulphur - With Oxidising Agents - When sulphur is mixed with potassium nitrate, potassium chlorate etc., it forms an explosive mixture. When struck or heated or ignited, the mixture explodes e.g. gun powde..

When sulphur is mixed with potassium nitrate, potassium chlorate etc., it forms an explosive mixture. When struck or heated or ignited, the mixture explodes e.g. gun powder. ..

Compounds - A compound is a pure substance that is formed by the combination of atoms of two or more elements. The atom in a compound is chemically combined in a fixed and constant proportion. When compounds are formed, atoms of two or more elements combine chemically, by either transfer or by shar..

. These are classified as organic compounds and their chemistry is known as "Organic Chemistry". Modern Organic Chemistry comprises the chemistry of carbon compounds existing naturally, as well some that are manmade. Much of organic chemistry is devoted to studying compounds of carbon and hydrogen ..

Summary - Oxygen and sulphur belong to group VI A. Oxygen shows a valency of -2, while sulphur shows a valency of -2, +4 and +6. Industrially oxygen is manufactured by fractional distillation of liquid air free of dust particles and CO 2 . Oxides of mercury, silver and lead decompose to give O 2 on..

. Transpiration is the loss of water from the aerial parts of the plant, mainly through the stomata of the leaves. Due to transpiration, the upper parts of the trees develop negative water potential. The water is then pulled up from the region of higher water potential in the lower regions. This is..
