Answer:
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

The answer is A: fleas and cats.
The yield of lithium chloride is 1.92 grams.
Option D.
<h3><u>Explanation:</u></h3>
In this reaction, we can see that 1 mole of lithium hydroxide reacts with 1 mole of potassium chloride to produce 1 mole of lithium chloride and 1 mole of potassium hydroxide.
Molecular weight of lithium hydroxide is 24.
Molecular weight of lithium chloride is 42.5.
So 24 grams of lithium hydroxide produces 42.5 grams of lithium chloride.
So, 20 grams of lithium hydroxide produces
grams =11. 29 grams of lithium chloride.
But this is when the yield is 100%.
But yield is 17%.
So the yield is 1.92 grams of lithium chloride.
