Answer: This is a single displacement reaction and the products are zinc chloride and hydrogen gas.
Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.
[tex]AB+C\rightarrow CB+A[/tex]
Element C is more reactive than element A.
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
[tex]AB+CD\rightarrow CB+AD[/tex]
Synthesis reaction is defined as the reaction in which smaller substances combine in their elemental state to form a larger substance.
[tex]A+B\rightarrow AB[/tex]
Decomposition reaction is defined as the reaction in which a large substance breaks down into smaller substances.
[tex]AB\rightarrow A+B[/tex]
For the given chemical reaction:
[tex]Zn(s)+2HCl(aq.)\rightarrow ZnCl_2(aq.)+H_2(g)[/tex]
The reaction is considered as single displacement reaction.
By Stoichiometry of the reaction:
1 mole of zinc metal reacts with 2 moles of hydrochloric acid to produce 1 mole of zinc chloride and 1 mole of hydrogen gas.
Hence, this is a single displacement reaction and the products are zinc chloride and hydrogen gas.
