Van der waal force α area of contact.

The above mathematical relation suggests that greater the contact area, greater is the van der waal force. 

As we move down the halogen group, area of contact between the molecule increses and hence van der waal forces also increases.

Hope this cleared your doubt, feel free to ask questions and have a nice day/night ahead! :)

Because the size of atoms increase as you move down the periodic table.

A cup of coffee(140g) cools from 75 degrees Celsius down to comfortable room temperature 20 degrees Celsius. How much energy doe
AVprozaik [17]

Energy releases to the surroundings = -32.2 kJ

<h3>Further explanation  </h3>

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

mass of coffee(m) = 140 g

∆T = temperature difference :

final temperature - initial temperature = 20-75=-55°C

specific heat coffee= specific heat water = 4.18 J/g° C  

The heat releases :

\tt Q=140\times 4.18\times -55\\\\Q=-32186~J\approx -32.2~kJ

Answer:

HI and I-

Explanation:

Hello there!

In this case, according to the acid ionization of hydroiodic acid:

HI+H_2O\rightarrow I^-+H_3O^+

Now, since the acid, HI, results in the conjugate base, I- and the base, H2O in the conjugate acid, H3O+, it is correct to assert that the acid-conjugate base pair is HI and I-
