Laws Governing Energy Transformations - The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says that 'energy can neither be creat..

1) Ammonium carbonate is a colourless crystalline solid. 2) It is soluble in water. 3) When exposed to the atmosphere, it undergoes dissociation and hence smells of ammoni..

It is a white powder. When mixed with water (1/3 of its mass), it evolves heat and quickly sets to a hard porous mass within 5 to 15 minutes. During setting, a slight expansion (about 1%) in volume occurs so that it fills the mould completely and takes a sharp impression. The p..

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...

1) It is soluble in hot water. 2) It is in the form of purple crystals. 3) On heating KMnO 4 decomposes to potassium manganate and oxygen...

Some physical characteristics of carbon dioxide are given below M.P B.P. Density (273K) CO bond length D Hf 216.4 K 194.5 K 1.977 g/L 116.3pm -393.5kJ/mol(5.2 atm) (Sublimes) CO 2 is a colorless gas with a faint pungent smell. It is about ..

1) Ammonium chloride is a colourless crystalline solid. 2) It is fairly soluble in water. Solubility of ammonium chloride in water is 41.4 g at 30 o C. 3) When it is dissolved in water, it absorbs heat and causes cooling. 4) When heated it undergoes dissociation to give ammonia and hydro..

1) K 2 Cr 2 O 7 is soluble in not water. 2) It is in the form of orange crystals. 3) On heating potassium dichromate decomposes and forms potassium chromate and chromic oxide...

Some of the synthetic detergents with a branched hydrocarbon chain have very low biodegradability. They are resistant to bacterial attack and are not fully degraded in sewage treatment units. Therefore, they cause water pollution when they are discharged into a river or any other water body. Phosp..

Which one of the statements satisfies transitive property? => If s = x and x = 4, then s = 4. or If v = x + 8 and x + 8 = m , then v = m or Both ( a ) and ( b ) or Neither ( a ) nor ( b )..
