The student wanted to find out what would happen when acids are
added to other substances such as metals. In an experiment, they
added magnesium to hydrochloric acid. The full, balanced equation is
provided below.
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
a) Provide an ionic and net ionic equation for this reaction between
magnesium and hydrochloric acid (also showing the cancelling
out of like species).
b) Briefly describe what the student would observe happening
during the reaction.
c) Name the salt formed by this reaction.
The student reacted another metal, calcium with hydrochloric acid.
d) Provide a full balanced equation (to include state symbols) and a
net ionic equation for this reaction.
e) The student noted that the same observations were seen in this
reaction. Provide a general word equation to show what
happens when a metal reacts with an acid.
