Why are hydrophobic molecules such as fats and oils unable to dissolve in watery solutions?
Maru [420]
Hydrophobic mplecules are unable to fissolve in watery solution becuse they dislike water.

Hydro= water
-phobic= fear

Hydrophobic= fear of water, or disliking water
*Think of it like this:
when you mix oil and water, do they mix, or does oil float at the top?

If your reply is "oil float to the top", then you're right. Oil and water DOES NOT mix together. Hope that help!

Electrolysis of molten lead bromide is carried out.
bearhunter [10]

Answer:

Read Below

Explanation:

Electrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes.

The bulb won't glow when the electrodes are embedded in solid lead bromide.  The bulb will glow when the material surrounding the electrodes is molten lead bromide. When an ionic compound is in the molten (liquid) form the positive and negative ions are free to move around.

Hopes this Helps :D
