Calculate the root mean square (rms) average speed of the atoms in a sample of xenon gas at 0.17atm and −52.°C .

Orlov [11]

Answer:

Check explanation

Explanation:

NB: In this question, we need the mass which is not given,so we have to make assumptions for the mass of xenon.

V^2(rms)= 3KT/m----------------------------------------------------------------------------------(1).

Where k= Boltzmann's constant =1.381×10^−23 m^2.kg/s^2.K.

T= temperature of the gas (in Kelvin), m= mass of one molecule of the gas (in kg).

Temperature, T= 273+(-52) =221K and V= the root mean square (rms).

Assuming that one mole of the gas has ;

m=0.084 kg. Hence, the mass of one molecule using Avagadro's number is;

0.084 kg ÷ 6.02×10^23 molecule.

Therefore, mass,m= 1.395× 10^ -25.

Therefore, from equation one above, we have;

V^2(rms)= 3 × 1.381×10^-23×221k/1.395×10^25.

V^2(rms) = 9.15603×10^-21/ 1.395×10^-25.

V(rms)= √ 6.56346236559139× 10^−46.

V(rms)= 2.56×10^-23 m/s.

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 $CH_{3}OH > CH_{3}Cl > CH_{4}$ .

What is found only in an experimental investigation?

andreev551 [17]

Experimental investigations<span> involve a process in which a "fair test" is designed and variables are actively manipulated, controlled, and measured in an effort to gather evidence to support or refute a </span>causal relationship<span>. Experimental investigations have a control group which does not receive any treatment. A classic example is "What is the effect of light color on plant growth?" In this experiment, the variable color of light is changed by the student. The student may compare red light to green light to natural light.

hope i helped ^_^</span>
