From the balanced redox equation of the reaction, the coefficient of OH⁻ is 8.
<h3>What is the balanced redox equation of the reaction?</h3>
A redox equation is the equation of a redox reaction in which oxidation and reduction occurs simultaneously.
The given redox reaction takes place in a basic solution
The balanced redox equation of the reaction is given below:
4 H₂O(l) + 3 S²⁻(aq) + 2 NO₃⁻(aq) ---> 3 S(s) + 2 NO + 8 OH⁻(aq)
In conclusion, a redox equation is balanced when oxidation and reduction occur to the same extent.

Answer:True
Explanation:
If a substance is pure, it will have exactly the same density as that reported for that particular substance in standard literature or vary within very narrow limits. Hence we can determine the purity of a gold sample by measuring it's density.
The answer for the following problem is mentioned below.
- <em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
- <em><u>Therefore the option is "D" (12.8 moles)</u></em>
Explanation:
Given:
Initial moles () = 7.51 moles
Initial volume () = 8.15 L
Final volume () = 13.9 L
To find:
Final moles of the gas
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
we know;
from the above mentioned equation,
V ∝ n
So,
=
where,
represents the initial volume
represents the final volume
represents the initial moles
represents the final moles
So,
=
= 12.8 moles
<em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
A bond is non polar if it is between same atoms and polar if it is between different atoms.
Same atoms are like two dogs of same strength pulling a bone towards towards each other. But when it’s different atoms it’s like a big dog and small dog then the bone is more towards bigger dog. So it’s the same way in bonds.
Bonds are made up of electrons, when the more stronger pulling atom is present than other the electrons are more towards it and as a result we have polar bond. There is development of a kind of a negative pole and a positive pole.
The stronger atom has electrons towards itself so it has a little more negative charge while the other atom has positive charge. This makes bond polar.
So just look for bond between two different atoms, it would be polar.
Look at the pic below to see the answer.
Marked with green is bond between same atoms... one carbon and another carbon so it is not polar and test marked with blue are polar.
Well the answer should have been 10 but since the bonds at 3 and 8 are two of same type we count only one of them.
The answer is 8... well the answer should be 10 otherwise... discuss it with ur teacher
