Answer:
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:
263 K
Explanation:
Assuming ideal behaviour and constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:
In this case:
We <u>input the data</u>:
- T₁ * 824.7 mL = 377 K * 575.45 mL
And <u>solve for T₁</u>:
