The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around.
2Na + ZnCl2 --------> 2NaCl + Zn
No. This equation is not balanced and does not even represent any reaction. The equation for the actual reaction between elemental zinc and chlorine is: Zn + Cl2 => ZnCl2.
The reaction is not possible.
Na2S(aq) + ZnCl2(aq) --> 2NaCl(aq) + ZnS(s)
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.
Zn + 2HCl --- ZnCl2 + H2 Mg + 2HCl --- MgCl2 + H2
Single replacement A+
single replacment
This is a redox reaction.
ZnCl2 + Mg
The reaction Zn + CuCl2 --> Cu + ZnCl2 is a single-replacement reaction.
No. This equation is not balanced and does not even represent any reaction. The equation for the actual reaction between elemental zinc and chlorine is: Zn + Cl2 => ZnCl2.
The reaction is not possible.
The reaction is: Zn + 2HCl = ZnCl2 + H2
Zn + 2HCl = ZnCl2 + H2
The products are sodium chloride and oxygen.
single-displacement reaction
The reaction is: Zn + 2 HCl = ZnCl2 + H2
