One classic chemistry experiment involves the reaction of hydrochloric acid and magnesium ribbon. A small piece of magnesium ribbon is placed in a test tube and hydrochloric acid is added to cover the magnesium. Students observe that the test tube gets hot, a gas (bubbles) is produced, and when a lit match is inserted in the mouth of the test tube, a loud "bark" is heard. This reaction is represented by the equation: Mg + 2HCl → MgCl2 + H2 The reaction can be described as both a reaction and a(n) reaction.

A) synthesis; endothermic
B) neutralization; exothermic
C) decomposition; neutralization
D) single replacement; exothermic
