Considering factors that affect that solubility which statement below true?

*with a few exceptions, the solubility of most solid solutes in water decreases as the solution temperature increases.

*the solubility of gases in water increases with increasing temperature.

*the solubility of a gas in any solvent is increased as the partial pressure of the gas above the solvent increases.

*substances with similar intermolecular attractive forces tend to be insoluble in one another.

part b

which of these is the best solvent for nonpolar solutes?

* acetone (ch3coch3)

*ethanol (ch3ch2oh)

*hexane (c6h14)

*water

Part A. The solubility of gases in water increases with increasing temperature.

Part B. Hexane (C₆H₁₄)

Part A

Considering factors that affect that solubility which statement below true?

Part B

Which of these is the best solvent for nonpolar solutes?

acetone (CH₃COCH₃)

ethanol (CH₃CH₂OH)

hexane (C₆H₁₄)

water

There is a general rule that states "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Thus, hexane, which is the least polar solvent, would be the best choice for nonpolar solutes.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
