Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) Mn²⁺(aq) + BiO₃⁻(aq) → MnO₄⁻(aq) + B
1 answer:
The balanced skeleton reactions are given below
2Mn²⁺(aq) +5BiO₃⁻(aq) + 14(aq) → 2MnO₄⁻(aq) + 5Bi³⁺(aq) + 7
(l)
The oxidising agent and reducing agents are Bi and Mn.
There are following steps involve in balance redox reaction in acidic medium .
- First divide the reaction into two half reactions .
- Balance the elements other than oxygen and hydrogen atom.
- Balance the oxygen atom by adding
on that side where number of oxygen atom is less .
- Balance the hydrogen atom by adding
on another side of in which water attached .
- Balance the charge by adding
.
- Add the two half reaction .
The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .

If excess carbon disulfide reacts with 450 mL of oxygen, 150 mL of carbon dioxide and 300 mL of sulfur dioxide gases would be produced respectively.
<h3>Stoichiometric calculation</h3>The reaction between liquid carbon disulfide and oxygen is represented by the equations below:
The mole ratio of oxygen to carbon dioxide and sulfur dioxide produced is 3:1:2.
Thus, for 450 mL oxygen, 1/3 x 450 = 150 mL of carbon dioxide will be required.
Also for 450 mL of oxygen, 2/3 x 450 = 300 mL of sulfur dioxide will be required.
