State the change in oxidation number to zinc in the following ionic half-equation and state whether zinc has been oxidised or reduced:
Zn(s) -> Zn2+(aq) + 2e-
State the change in oxidation number to manganese in the following ionic half-equation and state whether manganese has been oxidised or reduced:
MnO4- + 8H+ + 5e- -> Mn2+ + 4H2O
Is the following reaction an example of a disproportionation reaction?
Mg + 2HCl -> MgCl2 + H2
Is the following reaction an example of a disproportionation reaction?
2H2O2 -> 2H2O + O2
What is a systematic name?
