A student placed a small piece of magnesium ribbon in a conical flask and added
60 mL hydrochloric acid. The student observed that when the hydrochloric acid
came into contact with the magnesium ribbon, bubbles formed indicating the
release of hydrogen gas. The magnesium dissolved and magnesium chloride
solution formed. Based on the student's observations, which type of reaction
occurred?

Answer:

Single replacement reaction

Explanation:

Let us try to write down the reaction equation for the reaction of a magnesium  ribbon with hydrochloric acid.

Mg(s) + 2HCl(aq) ------> MgCl2(aq) + H2(g)

A single replacement reaction is a type of chemical reaction in which one element is replaced by another element in a compound.

In this reaction, magnesium replaced hydrogen to form the product. Hence it is a single replacement reaction.
