Answer:
A. Nonmetals have relatively high ionization energies.
Explanation:
Nonmetals have high ionization energies because they tend to gain electrons in order to fill their outer shell. Also, the electrons are closer to the nucleus and require more energy to remove them.

<span>If there are 15 mL in 1 tablespoon, then 3 tablespoons should have triple the volume as originally stated.
Note in all of the four choices, the units simplify to mL because tbsp x ml/tbsp = mL (tbsp/tbsp = 1)
The second and third choice give ultimately the same, incorrect value. The fourth option gives an incorrect fraction - there are not 15 mL for every tablespoon. The correct answer is 1 tbsp x 15mL/3tbsp</span>
