Fertiliser Technology Ammonium nitrate (is mixed with limestone) is not used as fertiliser as such, because It is a liquid at room temperature It is highly acidic in nature It is hygroscopic and explosive in nature Its nitrogen content is very less It is a liquid at room temperature It is highly acidic in nature It is hygroscopic and explosive in nature Its nitrogen content is very less ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Excessive use of chemical fertilisers causes shrivelling of the roots and wilting of the plant, because the Soil becomes too alkaline Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Osmotic pressure of the soil water becomes higher than that of the plant sap ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Dehydration of ammonium carbamate (to produce urea) is a/an __________ reaction. Catalytic Endothermic Exothermic Reversible Catalytic Endothermic Exothermic Reversible ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Though kinetics of ammonia synthesis dictates the use of low temperature for high equilibrium conversion, yet it is kept moderately high (550°C), because at low temperature Rate of reaction is very low None of these Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel Rate of reaction is very low None of these Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel ANSWER DOWNLOAD EXAMIANS APP
