What is minimum volume of oxygen required to react with 42.5 g of aluminum in the synthesis of aluminum oxide at stp?
natka813 [3]
<span>26.833 liters

Aluminum oxide has a formula of Al</span>₂O₃,<span> which means for every mole of aluminum used, 1.5 moles of oxygen is required (3/2 = 1.5).

Given 42.5 g of aluminum divided by its atomic mass (26.9815385) gives 1.575 moles of aluminum.

Since it takes 1.5 moles of oxygen per mole of aluminum to make aluminum oxide, you'll need 2.363 moles of oxygen atoms.

Each molecule of oxygen gas has 2 oxygen atoms, so the moles of oxygen gas will be 2.363/2 = 1.1815

Finally, you need to calculate the volume of </span>1.1815 <span>moles of oxygen gas.
1 mole of gas at STP occupies 22.7 liters of volume. Therefore,

1.1815 * 22.7 = </span>26.8 liters <span>of oxygen gas.

Which of the following statements best explains the observation that hydrogen fluoride has the highest boiling point of all the
olasank [31]

Answer:

c. HF can participate in hydrogen bonding.

Explanation:

<u>The boiling points of substances  often reflect the strength of the </u><u>intermolecular forces</u><u> operating among the molecules.</u>

If it takes more energy to  separate molecules of HF than of the rest of the hydrogen halides because HF molecules are held  together by stronger intermolecular forces, then the boiling point of HF will be higher than  that of all the hydrogen halides.

A particularly strong  type of intermolecular attraction is called the hydrogen bond, <em>which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond</em>, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.
