The chemical equation below is correctly balanced. 4 Al + 3 O2 → 2 Al2O3

How many moles of Al2O3 will be formed when 27 grams of Al reacts completely with O2?

0.35moles

Explanation:

when 156g of Al reacts with 2molesof Al2O3 then 27g of Al reacts with what then u cross multiply and solve ur answer

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
