<u>Answer:</u> The partial pressure of sulfur dioxide gas in the flask is 160 mmHg
<u>Explanation:</u>
We are given:
Moles of sulfur dioxide gas = 0.25 moles
Moles of methane gas = 0.50 moles
Moles of oxygen gas = 0.50 moles
To calculate the mole fraction of sulfur dioxide, we use the equation:
The partial pressure of a gas is given by Raoult's law, which is:
where,
= partial pressure of sulfur dioxide gas
= total pressure = 800 mmHg
= mole fraction of sulfur dioxide = 0.2
Putting values in above equation, we get:
Hence, the partial pressure of sulfur dioxide gas in the flask is 160 mmHg
Answer:
Atoms making liquids have less attraction than solids, but more than gases
Explanation:
The attraction between atoms in different molecules in a solid is very strong due to strong intermolecular forces present in a solid. However, such intermolecular forces are weaker in liquids than in solids.
This implies that the solid has higher intermolecular forces of attraction compared to gases and liquids. Based on the negligible degree of intermolecular forces between them, a gas has the weakest intermolecular forces hence the atom has very minimal interaction between them.

a, c, and d are all chemical properties because they give information about how a substance will behave in the given reaction, and can’t be found without the substance undergoing some sort of chemical reaction. b, on the other hand, is a physical property—it can be determined without changing the substance’s chemical composition.
