Generally speaking only certain molecules will dissolve in water to begin with. The old phrase "like dissolves like" or "birds of a feather flock together" is very true with respect to what degree solutes are soluble or miscible in different solvents. At very low concentrations, almost all molecules are somewhat soluble in all solvents. But by trend, ionic and polar solutes are more soluble in polar solvents and non-polar molecules are soluble in non-polar (mostly organic) solvents. The units of concentration we just discussed are used to describe the degree to which a solute is soluble in a solvent.
When you place a non-polar molecule in a polar solvent (like oil in water) the molecules try to minimize surface contact between them. (like you and a guy with a cold on an elevator). This is actually the basis for the cells in our bodies. The lipids (oily fatty acids) form our cell membranes so that their non-polar tails face inward away from the polar cytoplasm and the polar heads face towards the polar cytoplasm.
Explanation:
sulphur has a low melting point.
sulphur has a low boiling point thus it can be extracted by pumping hot water which turns it ito solution form
I BELIEVE THAT VAPORIZATION THAT <span>element or compound is a phase transition from the liquid phase to vapor.
AND
EVAPORATION </span>a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.
Answer:
Potassium
Explanation:
The atom with the largest atomic radius is potassium from the given list.
The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between nuclei in the solid metal state.
Across a period in the periodic table, atomic radii decreases progressively from left to right.
This is due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
Answer:
Choose all the answers that apply. Energy _____. Moves in waves, cannot be created, can be destroyed, is the ability to do work, can change form.
I hope this is correct for you. I am sorry if i am wrong.
Hope this helps!
Have a great day and stay safe! :))))
