Answer:
Order of increasing strength of intermolecular attraction:
> 
> 
> Ar
Explanation:
can form hydrogen bond as H atom is attached with electronegative atom O.
Rest three, , , Ar are non-polar molecules.
In non-polar molecules, van der Waal's intermolecular forces of attractions exist. Hydrogen bonding is stronger intermolecular attraction then van der Waal's intermolecular forces of attraction, hence, has strongest intermolecular attractions.
Ar will have least intermolecular attraction, as it behaves almost as ideal gas and there is no intermolecular attraction exist between molecules of ideal gases.
Molecular size and mass of is high as compared to .
van der Waals intermolecular forces of attraction increases with increase in size.
Therefore,
Order of increasing strength of intermolecular attraction will be:
> > > Ar

please thank and brainlest!
Explanation:
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions. ... It is known as the titrant.
Answer:
Because your body has built-in resistance to certain gases, no matter the size of the gas cloud.
That is why we are able to stay non-inert to these types of gases, like Carbon dioxide.
