8.0 dm of NO is mixed with 6.0 dm3 of O, at room temperature and pressure (RTP). The reaction below takes place until one of the reactants is used up.

2NO(g) + O2(g) + 2NO,(9)

What is the volume of the mixture at RTP after the reaction has taken place?

A)8.0 dm3

B)10.0 dm3

C)12.0 dm3

D)14.0 dm3

The volume of the mixture after the reaction is  10 dm³

The correct answer to the question is Option B. 10 dm³

The above is simply a demonstration of Gay-Lussac' law. The volume of the mixture after the reaction can be obtained as follow:

                            2NO(g) + O₂ —> 2NO(g)

Combining Vol:   2 dm³  :  1 dm³   :  2 dm³

Before reaction:  8 dm³  :  6 dm³  :  0

During reaction:  8 dm³  :  4 dm³  :  8 dm³

After reaction:    0 dm³  :  2 dm³ :  8 dm³

The Volume after the reaction = 2 + 8 = 10 dm³

B)10.0 dm3

Explanation:

Now we have to apply Gay-Lussac's law which states that gases combine in simple volumes provided the temperature and pressure remain constant.

                                               2NO(g) + O2(g) >2NO

combining volumes                2            :   1               :  2

Volumes before reaction       8.0            6.0               0.0

Reacting volumes                   8.0            4.0                8.0

Volumes after reaction           -                 2.0              8.0

Therefore;

Total volume after reaction = 2.0 + 8.0 = 10.0 dm^3

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
