Potassium reacts with aluminum bromide to produce aluminum and potassium bromide. You will generate moles of aluminum when you react 0.372 moles of potassium.

You will generate 0.124 moles of aluminum when you react 0.372 moles of potassium

Explanation:

Determine the reaction:

3K + AlBr₃ → Al + 3KBr

Ratio is 3:1

3 moles of K can produce 1 mol of Al

So, 0.372 moles of K, may produce (0.372 .1) /3 = 0.124 moles of Al

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
