Solubility of Ammonium nitrate is?
Explanation: Solubility of Ammonium nitrate is 389.6.
What is the molecular weight of Ammonia?
Explanation: The formula of Ammonia is NH3, Weight of nitrogen is 14 and weight of hydrogen is 1.Weight of Ammonia is 14+ 3*1 = 17.
Which of the mentioned statements regarding the solubility of ammonia is true?
A. Insoluble in water
B. Highly Soluble in water
C. Soluble in Chloroform
D. Highly Soluble in water and soluble in Chloroform
Explanation: Ammonia is highly soluble in water and is soluble in solvents like chloroform, ether, ethanol, and methanol.
Which one is the highest end use for ammonia?
B. Direct application as fertilizer
C. Nitric acid
Explanation: The end uses for ammonia worldwide are as follows direct application as fertilizer- 25%, urea- 21%, nitric acid-12% and acrylonitrile – 3%.
Ammonia production is favoured by which following factor?
A. High temperature and low pressure
B. Low temperature and low pressure
C. Low temperature and high pressure
D. High temperature and high pressure
Explanation: From the equilibrium standpoint this ammonia production reaction is favoured by low temperature and high pressure according to Le chatelier’s principle. At low temperature the rate of backward reaction will more than forward reaction.
