You collect a sample of gases from an indoor pool area. the sample contains air and water vapor. the total pressure is 100.18 kilopascals, and the partial pressure of the water vapor is 3.36 kilopascals. what is the partial pressure of the air in the sample? a. 29.8 kpa b. 51.77 kpa c. 96.82 kpa d. 103.54 kpa e. 337 kpa

C. 96.82 kPa

Explanation: According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

Thus

Given:

Thus

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.
