Answer:
Explanation:
Hello,
In this case, since the neutralization reaction between HCl and NaOH is:
We notice a 1:1 molar ratio, for that reason, at the equivalence point we find:
Thus in terms in molarities one could compute the concentration of HCl in the old bottle for the used NaOH for the neutralization as:
This value is lower than 37% HCl that in molarity is about 12 M, such difference is due to its high volatility.
Best regards.

Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic
For N and Se,
E.N of Nitrogen = 3.04
E.N of Selenium = 2.55
________
E.N Difference
0.49 (Weakly Polar Covalent)
As you have not provided remaining pairs, so if you have any of them, follow the method as mentioned above.
Covalent compounds share with each other, whilst Ionic compounds take from each other.
Covalent compounds are composed of 2 or more NONMETALS.
So, it would be CO, since the rest of the compounds contain metals in them.
