The statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.
<h3>What are intermolecular forces?</h3>
The term intermolecular forces are the force that hold matter together in a particular state such as solid liquid or gas. The more the electrons present, the greater the polarizability and the greater dispersion forces at work.
Thus, the statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.

Answer:
677.7 mmHg
Explanation:
The first empirical study on the behaviour of a mixture of gases was carried out by John Dalton. He established the effects of mixing gases at different pressures in the same vessel.
Dalton's law states that,the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the individual gases present in the mixture of gases. When a gas is collected over water, the gas also contains some water vapour. The partial pressure of the gas will now be given as; total pressure of gas mixture - saturated vapour pressure of water (SVP) at that temperature.
Given that;
Total pressure of gas mixture = 692.2 mmHg
SVP of water at 17°C = 14.5 mmHg
Therefore, partial pressure of oxygen = 692.2-14.5
Partial pressure of oxygen = 677.7 mmHg
Answer:
It cannot conduct electricity, however adding salt or sugar will make the water have impurities/other substance making it easier to conduct electricity
Explanation:
Distilled water by itself does not contain impurities, thus, it cannot <em>conduct </em>electricity.
When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely, increasing the conductivity.

Explanation:
In laboratory, carbon dioxide is not obtained from the air, carbon dioxide is prepared from carbonates by adding acids to the carbonates. In this experiment carbon dioxide is prepared by the reaction of marble with hydrochloric acid.
