cause sience is my favorite subject if you dont belive look at answer above
there are 6 moles of oxygen in Zn(No3)2
The answer to your question is: ΔH = -283 kJ/mol, first option
Reaction
CO + O₂ ⇒ CO₂
ΔH = ∑H products - ∑H products
ΔH = -393.5 - (-110.5 + 0)
ΔH = -393.5 + 110.5
ΔH = -283 kJ/mol
d
15 X 6 X 10 = 900 cm³
