Nitroglycerin decomposes violently according to the balanced chemical equation below. 2 C_3H_5(NO_3)_3(l) rightarrw 3 N_2(g) + 1/2 O_2(g) + 6 CO_2(g) + 5 H_2O(g) Which of the following statements concerning this reaction is/are CORRECT? Two moles of nitroglycerine will produce three moles of nitrogen and five moles of water. Four molecules of nitroglycerine will produce one molecule of oxygen and twelve molecules of carbon dioxide. Six grams of nitroglycerin

Explanation / Answer

23. The right answer is option b: oxygen

The reaction given is an example of redox reaction. In this reaction carbon is oxidized to carbon dioxide and oxygen is reduced to water.

Oxygen is the oxidizing agent because it has the ability to oxidize other substances. In this case it oxidizes carbon to carbon dioxide. Hence it is the right answer.
