Elements higher on the list are more reactive than metals lower on the list and are able to replace
metals in a single replacement reaction. Below is the activity series.
Complete the following statement with all the responses that apply.
A student drops a copper (Cu) penny into a solution of hydrochloric acid (HCl). The copper ...
(1 point)
will replace the hydrogen because copper is more reactive than hydrogen.
will replace the hydrogen because it is lower on the activity series than hydrogen.
will not replace hydrogen because hydrogen is lower on the activity series than it.
will not replace the hydrogen because the copper is less reactive than hydrogen.
1 answer
The correct completion of the statement is:
will not replace the hydrogen because the copper is less reactive than hydrogen.
This is because in the activity series, copper (Cu) is lower than hydrogen (H), indicating that copper is less reactive and cannot displace hydrogen from hydrochloric acid.
