Ethanol and water have different boiling points, and when mixed they form a homogeneous mixture. by which process could the mixture be separated? a. pouring off the ethanol layer b. distillation c. stirring the mixture thoroughly d. filtration

the answer your looking for is a because it latterly says it right there. look closer to what its asking you

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.

let that person have a turn to speak : )
