Ammonia reacts with sulphuric acid to give the fertilizer ammonium sulphate. calculate the volume of ammonia at s.t.p to from 59 g of ammonia sulphate
Answers
2NH3(g)+H2SO4(aq)----->(NH4)2SO4(aq)
How many kilograms of NH3 are needed to produce 2.10*10^5kg of (NH4)2SO4? (scientific notation).
2) Nitroglycerin (C3H5N3O9) is a powerful explosive its decomposition may be represented by
4C3H5N3O9--->6N2+12CO2+10H2O+O2
this reaction generates a large amount of heat and gaseous products. It is the suggen formation of these gases, together with their rapid expansion, that produces the explosion.
(A) What i the maximum amount of O2 in grams that can be obtained from 2.50*10^2g of nitroglycerin? (g)
(B) Calculate the percent yield in this reaction if the amount of O2 generated is found to be 7.87g. (%)
3) When potassium cyanide (KCN) reacts with acids a deadly poisonous gas, hydrogen cyanide (HCN) is given off
KCN(aq)+HCl(aq)--->HCN(g)+KCl(aq)
If a sample of 0.380g of KCN is treated with an excess of HCl, calculate the amount of HCN formed in grams.

Answer:
1) The fertilizer ammonium sulfate (NH4)2SO4. is prepared by the reaction between ammonia (NH3) and sulfuric acid:
2NH3(g)+H2SO4(aq)----->(NH4)2SO4(aq)
How many kilograms of NH3 are needed to produce 2.10*10^5kg of (NH4)2SO4? (scientific notation).
