A 6.0 L sample of gas at 300 K cools down until its volume is 3.0 L. Assuming pressure is constant, what is the final temperature of the gas?

350 K
250 K
200 K
150 K

false

because it does not have the potential to be entirely used up

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.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
