Expert Solution

Homogenous mixure:- A mixture in which all the compnents are distributed in same proportion throought the entire volume.

example - wine, water, salt water and air.

Heterogenous mixure:- A mixture in which all the components are mixed non uniformly.

since bubbles get formed when we add the beer in a glass hence the perpotion gets disturbed and that's what makes it a heterogenous mixture.

hence the final answer is BEER.

Q2:- the final answer is b.

Q3:- the final answer is c.

Rank each substance above from strongest to weakest intermolecular force. Do not look up these substances' physical properties...determine the ranking based on general intermolecular force principles. If you predict an "anomaly" (i.e. a "LDF only" molecule with greater intermolecular forces than a dipole-dipole or hydrogen bonding molecule), you must briefly state your reasoning. Please justify why you put each molecule in its order. CCl4 BH3 SF4 CH3NH2 CO2 N2O (NNO) CH3OH
