Which reactions are single displacement reactions?

Answer:
- [tex]SnO_2+2H_2-->Sn+2H_2O[/tex]
- [tex]2Al+6HCl-->2AlCl_3+3H_2[/tex]
Explanation:
Hello,
Single displacement reactions happen when one compound reacts with a single element or molecule to yield one compound and a single element or molecule as well by exchanging the cation or the anion depending on the case, in such a way, the reactions that accomplish the definitions are:
- [tex]SnO_2+2H_2-->Sn+2H_2O[/tex]
- [tex]2Al+6HCl-->2AlCl_3+3H_2[/tex]
Best regards.
