yes
as zinc is oxidised and hydrogen is reduced
This is a redox reaction.
Redox reaction.
Zn + PbCl2 --> Pb + ZnCl2
Oxidation is a redox reaction.
No. Zn + 2HCl = ZnCl2 + H2
This is a redox reaction.
single replacment
yes
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
No, it is not a redox reaction. None of the oxidation numbers changes during the reaction. You have to determine the oxidation number for each element and see if it changes from reactant side to product side. If the oxidation number doesn't change, it is not a redox reaction.
Cu and ZnCl2 are being produced.
Sodium (Na) has been reduced.
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
Redox reaction.
Zn + PbCl2 --> Pb + ZnCl2
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
Oxidation is a redox reaction.
