2.47 moles are produce if 85g of N2 react with 180g of Mg
1 A1Br3 + 3 K = 3 KBr + 1 A1
<span>subshells have two reasons of stability-
</span><span> 1) half filled and full filled subshells lead to symmetry as symmetry always increases stability in the nature.
</span>2)<span> in half filled and full filled subshells there are maximum no Of exchanges so exchanges releases energy so it increase stability.. Exchange of e-s also can b understood as delocalization of e-s which is similar like resonance and resonance always increases stability</span>
It’s jingju because it was established in 1955
