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 .

<h2>Hello!</h2>
The answer is: The new pressure is 1.67 atm.
<h2>Why?</h2>From the statement, we know that the temperature remains constant and the gas volume is changing, meaning that the new pressure will be different than the first pressure.
Since the temperature remains constant, we can calculate the new pressure using the Boyle's Law.
The Boyle's Law states that:
Where,
P is the pressure of the gas.
V is the volume of the gas.
Then, the given information is:
Remember, 1 L is equal to 1000 mL.
So,
So, calculating the new volume, we have:
Hence, the new pressure is 1.67 atm.
