For each of the following:
• Assign Oxidation States (Numbers) to each atom in reactants
and products
• Identify the species being reduced and the species being
oxidized
• Balance each redox reaction using the Half-Reaction method
O2 + ClO-2 -->
H2O + ClO2
Al + MnO-4 --> MnO2 +
Al(OH)-4
NO2- + Al --> NH3 +
AlO2
Also could you please explain how you get the oxidation numbers,
i am having trouble with that as well as to how...
Assign the oxidation numbers to each species as a reactant and
as a product.
Balance equation _2_KCLO3(s)-->__2_KCl(s) + __3__
O2
K in KCLO3(S)
K in KCL(s)
Cl in KCLO3(S)
Cl in KCL (s)
O in KCLO3 (S)
O in O2
In this reaction __________ is oxidized and __________ is
reduced
Assign oxidation states to each of the atoms in the reactants
and products listed below. Then balance the equation using the
oxidation state method. What is being oxidized and reduced? What is
the oxidizing agent and the reducing agent?
H2C2O4(aq) +
MnO41-(aq) + H+(aq) --->
CO2(aq) + Mn2+(aq) + H2O(l)
For the following reaction KClO3---->KCl+1/2 O2 assign
oxidation states to each element on each side of the
equation...reactants and products. Which element is oxidized? Which
element is reduced?
Reactants for K, Cl, and O please.
