Answer:

$\boxed {\boxed {\sf C. \ 12 \ oxygen \ atoms }}$

Explanation:

We are given the chemical formula:

$Fe(ClO_4)_3$

There are 3 elements here:

Fe: Iron
Cl: Chlorine
O: Oxygen

The question asks for the number of oxygen atoms, so we can just focus on the O in the formula.

The O has a subscript of 4, indicating there are 4 oxygen atoms in the compound. But the compound is also enclosed in parentheses with a subscript of 3. Therefore, there are 3 of the compounds with 4 oxygen atoms.

We can multiply 3 and 4.

3*4= 12

There are <u>12 oxygen atoms.</u>

Using your knowledge of chemistry and the information in Reference Table H, which statement concerning propanone and water at 50

stiv31 [10]

The answer is (2) higher vapor pressure and weaker intermolecular forces. Propanone has a lower boiling point, so it is more volatile than water. Propanone's vapor pressure is, therefore, higher than that of water at 50 degrees Celsius. Propanone is more volatile due to the fact that the intermolecular forces that hold its molecuels together are not as strong as those that hold together molecules of water. Since the IMFs are weaker, it takes less thermal energy to break individual molecules free of each other.
