100 NaNO2 + NH4Cl = NaCl + NH4NO2 (No balancing required) Balance the following equation - NaNO2 + NH4Cl = NaCl + NH4NO2	100 False. It cannot be used in systems having copper pipes. True or False - Liquid Ammonia cannot be used in systems having Chromium pipes	100 Chlorofluro carbon (CFC) The refrigerant responsible for majority of Ozone depletion.	75 Acids are compounds which contain one or more hydrogen atoms and when dissolved in water, produce hydronium ions. What are acids?
200 False. It's the opposite True or False - NH4NO3 is used in dry cells, while NH4Cl is used in the making of explosives	200 5700 calories per mole at -33 degrees Celsius. What is the amount of heat liquid ammonia takes in order to vaporize?	200 NH2CONH2 Chemcial formula of Urea	75 True True Or False - Calcium Oxide is an electrovalent compound .
300 The reaction needs to be carried out at 150 Degrees C and at 150 atm. Urea is an important nitrogenous fertilizer obtained by treating ammonia with carbon dioxide. What are the 2 conditions required in the reaction in order to obtain Urea?	300 False - Highly volatile, high latent heat of evaporation. True or False - Liquid Ammonia is used as a refrigerant due to its low volatile nature and and high latent heat of evaporation.	300 NH4)2CO3 - Used as smelling salt for revival of a person NH4NO3 - Used in making of explosives Differentiate between Ammonium carbonate and ammonium nitrate based on their uses for manufacturing.	75 Haber's Process The process (not lab prep) used in manufacturing of Ammonia.
400 It gives coloured metallic hydroxide precipitates. Ammonia is used as an important laboratory reagent in qualitative analysis. Why?	400 It emulsifies/dissolves fats, grease etc. Aqueous Ammonia is used to remove grease or to clean tiles and windows due to a particular characteristic it possesses. What is the characteristic?	400 It was Liquid Ammonia, which in large concentration is poisonous Mr. X woke up in the middle of the night on smelling a weird odour nearby, coming from a large industrial refrigerator. What could it have been? Had he been in more contact with the chemical, what would have happened?	75 - Prevents or minimizes back-suction of water - Provides a larger surface area for absorption of HCl gas Why is the funnel arrangement used in the lab preparation of Hydrochloric acid?
