Question

Classify the following transformation as a reduction, oxidation, or neither.

C3H8O=C3H6O Br+2e-=2Br- NO2=NO Mn=Mn2++2e-   Ti=TiO2   C4H8O=C4H10O

Part B

Classify the reactants in these chemical equations based on whether they are oxidized or reduced.

Classify the following transformation as a reduction, oxidation, or neither. C3H8O=C3H6O Br+2e-=2Br- NO2=NO Mn=Mn2++2e- Ti=TiO2 C4H8O=C4H10O Part B Classify the reactants in these chemical equations based on whether they are oxidized or reduced. Cr2O3+2Al?2Cr+Al2O3 2C2H6+7O2?4CO2+6H2O Mg+Cu2+?Mg2++Cu

Explanation / Answer

C3H8O=C3H6O Oxidised

Br+2e-=2Br- Reduced

NO2=NO reduced

Mn=Mn2++2e- Oxidised

Ti=TiO2 Oxidised

C4H8O=C4H10O Reduced

b) Cr2O3+2Al= 2Cr+Al2O3 ; Cr2O3- Reduced & Al- Oxidised

2C2H6+7O2= 4CO2+6H2O ; C2H6 -Oxidised & O2- Reduced

Mg+Cu2+= Mg2++Cu ; MgOxidised & Cu2+ Reduced
