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
