<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>
0.65×100=65g
100 is the mass of one mole of caco3 in grams.
Balanced chemical reaction: Fe₂O₃<span> + 2Al → 2Fe + Al</span>₂O₃.
Fe₂O₃ is iron(III) oxide.
Al is aluminium.
Fe is iron.
Al₂O₃ is aluminium oxide.
In thermite reaction<span> elemental aluminium reduces the iron (III) oxide or some other metal oxide.
Mole ratios from chemical reaction:
n(</span>Fe₂O₃) : n(Al₂O₃) = 1 : 1.
n(Fe₂O₃) : n(Al) = 1 : 2.
n(Fe₂O₃) : n(Fe) = 1 : 2.
Answer:
C - raising the temperature of a gas
Explanation:
as you raise temperature, kinetic energy rises, and so does pressure
