Nitroglycerine is an explosive compound. Consider the energy profile of the decomposition of nitroglycerine. Which statement is true?
 
A) Nitroglycerine has less chemical energy than its products.
B) Mass is created during this chemical reaction.
C) Gases and energy are produced during the decomposition of nitroglycerine.
D) The products of this reaction have more mass and energy than the reactants.
E) None of the above are true.

The Solution...

The energy profile of this reaction shows that nitroglycerine has more chemical potential energy than the products of the decomposition reaction.
Mass can not be created or destroyed during chemical reactions so options D and B are wrong.
