Question
12. The decomposition of nitroglycerine is an explosive reaction that produces four different gases.
How many moles of water will be formed when 11.35 g of nitroglycerine decomposes according to,
4 C3H5O9N3 => 12 CO2 + 6 N2 + O2 + 10 H2O?
12.5 mol water
2.0 mol water
0.05 mol water
0.125 mol water
0.02 mol water

Sulfur dioxide reacts with chlorine to produce thionyl chloride and dichlorine oxide.
SO2(g) + 2Cl2(g) SOCl2(g) + Cl2O(g).
If 1.200 mol of Cl2 reacts with SO2, how many moles of Cl2O are formed?
2.400 mol
0.600 mol
0.300 mol
1.800 mol
1.200 mol
10.
Consider the reaction between aluminum sulfate and barium chloride shown. Which of the statements is FALSE?
Al2(SO4)3 + 3 BaCl2 3 BaSO4 + 2 AlCl3
this is neither a synthesis nor a decomposition reaction
aluminum chloride is a product of the reaction
the fact that the number of each type of atom on each side is equal is related to the Law of Conservation of Mass.
there will be 3/2 times as many aluminum chloride molecules made as there are molecules of barium chloride used.
6 "molecules" of barium chloride will make 6 "molecules" of barium sulfate
a.12.5 mol water
b.2.0 mol water
c.0.05 mol water
d.0.125 mol water
e.0.02 mol water
Explanation / Answer
12. The decomposition of nitroglycerine is an explosive reaction that produces four different gases.
How many moles of water will be formed when 11.35 g of nitroglycerine decomposes according to,
4 C3H5O9N3 => 12 CO2 + 6 N2 + O2 + 10 H2O?
mol of nitroglycerine = mass/MW = 11.35/227.0865 = 0.04998095 mol
ratio is 4:10 so
10/4*0.04998095 = 0.124952 mol of water expected
