This is a redox reaction.
double replacement
MgBr2 + Cl2 --> MgCl2 + Br2
The equation is 4 Zn + 10 HNO3 -> 4 Zn(NO3)2 + N2O + 5 H2O.
Zn(s) + O2(g) --> ZnO(s)
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
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
This is a redox reaction.
double replacement
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.
MgBr2 + Cl2 --> MgCl2 + Br2
The equation is 4 Zn + 10 HNO3 -> 4 Zn(NO3)2 + N2O + 5 H2O.
Mg + MgCl2
Zn(s) + O2(g) --> ZnO(s)
Magnesium hydroxide plus hydrochloric acid yields magnesium chloride plus water. Mg(OH)2 + 2HCl = MgCl2 + 2H2O
MgBr2 + Cl2 yields MgCl2 + Br2 is an example of an anionic single replacement chemical reaction.
Zn + 2HCl --- ZnCl2 + H2 Mg + 2HCl --- MgCl2 + H2
