How would you separate a mixture of oil, water and sand?plz help

1) Filter the mixture, Sand will remain on the filter paper. 2) Then pour the mixture of mustard oil and in separating funnel. Water will settle down at bottom and mustard oil will float on it. Then open the stopcock of the separating funnel and pour out the lower layer of water.

Explanation:

answer; i believe the correct answer is (solid gold);

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.
