KIO4 is an example of polyatomic ion.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge on the ion.
The charge on this polyatomic ion is 0.
To get the oxidation number of I, we will let x as the oxidation number of I.
We can get the oxidation number of Iodine by solving like this;
KIO4 : (+1) + x + 4(-2) = 0
(+1) + x - 8 = 0
x - 7 = 0
x = +7
Therefore, the oxidation number of iodine atom in KIO4 is +7.

Answer:
A. 2,3 BPG
Explanation:
2,3-bisphosphoglycerate (BPG), otherwise known as 2,3-DPG, enables the transition of hemoglobin from a very high-oxygen-affinity state to a reduced-oxygen-affinity state.
Tissues hemoglobin oxygen affinity is reduced by numerous physiological factors including.
1. Temperature Increased,
2. Carbon dioxide,
3. Acid and
4. 2,3-Bisphosphoglycerate (2,3-BPG)
all of which can contribute to decrease the oxygen affinity of hemoglobin which favours unloading and increased oxygen availability to our body cells.
Answer:
Molarity = 2.3 M
Explanation:
Molarity can be calculated using the following rule:
Molarity = number of moles of solute / volume of solution
1- getting the number of moles:
We are given that:
mass of solute = 105.96 grams
From the periodic table:
atomic mass of carbon = 12 grams
atomic mass of hydrogen = 1 gram
atomic mass of oxygen = 16 grams
Therefore:
molar mass of C2H6O = 2(12) + 6(1) + 16 = 46 grams
Now, we can get the number of moles as follows:
number of moles = mass / molar mass = 105.96 / 46 = 2.3 moles
2- The volume of solution is given = 1 liter
3- getting the molarity:
molarity = number of moles of solute / volume of solution
molarity = 2.3 / 1
molarity = 2.3 M
Hope this helps :)
