Arrange these compounds by their expected boiling point. Highest boiling point Lowest boiling point CH3OH, CH3CI CH4.
PSYCHO15rus [73]

Answer: The given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.

Explanation:

The temperature at which vapor pressure of a substance becomes equal to the atmospheric pressure is called boiling point.

Stronger is the intermolecular forces present the atoms of a molecule more heat will be required by it to break the bond between its atoms. Hence, more will the boiling point of the molecule.

In CH_{3}OH (methanol), there is hydrogen bonding present which is a stronger force. So, it will have highest boiling point as compared to CH_{3}Cl and CH_{4}.

In CH_{3}Cl (chloroform), there is more electronegative atom attached (Cl) is attached to less electronegative atom (C and H). So, electrons are more pulled towards the chlorine atom. So, boiling point of  CH_{3}Cl is more than methane (CH_{4}).

Thus, we can conclude that given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.

Can anyone tell me 5 reactions of metals with nonmetals?​
jeyben [28]

non-Metals:

Nitrogen.

Oxygen.

Helium.

Sulfur.

Chlorine.

Explanation/Answer:

Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.

PLS HELP! 50 PTS!

Answer:

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

Explanation:

<em>The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.</em>

<u>According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.</u>

In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.
