B. Fluorine
Explanation:
Nonmetallic character increases from <em>bottom to top</em> in a Group and from <em>left to right</em> in a period (see image).
Thus, the most nonmetallic elements are at the <em>upper right corner</em> of the Periodic Table.
We ignore the noble gases, because they are quite unreactive.
So, the element that most “wants” an electron is fluorine.
Answer:
Molarity of solution is 0.311 M
Explanation:
Neutralization reaction:
According to balanced reaction, 1 mol of neutralizes 2 moles of
Number of moles of in 13.8 mL of 0.191 M
solution =
=
Let's assume molarity of solution is C (M) then-
Number of moles of in 17.0 mL of C (M)
solution =
=
Hence,
or,
So, molarity of solution is 0.311 M
