H2 + MgCl2 → 2HCl + Mg
Synthesis
Decomposition
Single Replacement
Double Replacement
Hint:
Single displacement reaction can be termed as when only one displacement take place in a reaction.
The correct answer is: Single Replacement
The word displace means to push out. A more reactive element can displace a less reactive element out of its compound during a chemical reaction, this reaction is termed as displacement reaction. Single displacement reaction can be termed as when only one displacement take place in a reaction. A single displacement reaction is a chemical reaction which occurs when one part of a compounds is exchanged with another element forming a new compound.
