Amotorist travels a distance of 55.0 mi for 4.25 h how fast did he travel

The answer is actually 13 you divide 55 miles by the hours to get 12.9 which you round to 13

Hello there,

a motorist travels a distance of 55.0 mi for 4.25 h how fast did he travel

13

Divide 55 by 4.25 =12.9

Than, round it and you'll get 13 :)

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.
