Answer:
D) single replacement
Explanation:
Given reaction:
Mg + 2HCl → MgCl₂ + H₂
The reaction shown above is a single displacement reaction.
In a single displacement reaction, a more reactive atom displaces another from a given compound.
The comparison here is between Mg and H.
On the activity series, Mg is higher and more reactive, it will displace H from the solution of HCl. This
This reaction type is called a single replacement reaction.
A. add a catalyst is the correct answer.
A catalyst never takes part in the reaction, so it does not affect the reaction.
