Electrolysis of water Steam reforming of naphtha Natural gas cracking Cryogenic removal of H₂ from coke oven gas Electrolysis of water Steam reforming of naphtha Natural gas cracking Cryogenic removal of H₂ from coke oven gas ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Excessive use of chemical fertilisers causes shrivelling of the roots and wilting of the plant, because the Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic ANSWER DOWNLOAD EXAMIANS APP
