The compound nitrogen have most positive oxidation state is NO₂. The correct option is b.
<h3>What is oxidation state?</h3>
The total number of electrons gained or lost by an atom in order to form a chemical bond with another atom.
The charge on an ion is equal to the sum of the oxidation states of all the atoms in the ion. A substance's more electronegative elements are given a negative oxidation state.
A positive oxidation state is assigned to the less electronegative element.
Thus, the correct option is b, NO₂.

Can you please explain what the BTB is so I may help ya?
Only these values can exist... N=? L=0 to N-1 M=+ to - L S=+ or - 1/2
Answer:
To make a 3.50 M solution, 38.5 moles of solute will be needed if 11 liters of solution are required.
Explanation:
Molarity is defined as a concentration unit that indicates the number of moles of solute per liter of solution. That is, it indicates the number of moles of solute that are dissolved in a given volume. Then, the molarity is calculated by dividing the moles of the solute by the liters (volume) of the solution:
Molarity is expressed in units ().
So, knowing the definition of molarity, you can apply a rule of three as follows: if by the definition of molarity in 1 L of solution there are 3.5 moles of solute, in 11 L of solution how many moles of solute are there?
moles=38.5
