Atomic mass is the sum of all isotopes' abundace-mass product. First start by finding the abundance of isotope B (isoB% = 100- isoA% - isoC%). Now plug in all known values into (mass = Amass*A% + Bmass*B% + Cmass*C%) and solve for Bmass
Answer:
–1065.25 KJ of energy.
Explanation:
From the question given above, the following data were obtained:
4FeO + O₂ —> 2Fe₂O₃ ΔH = –560.66 kJ
From the balanced equation above,
The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.
Finally, we shall determine the amount of heat energy released when 3.8 moles of Fe₂O₃ are produced. This can be obtained as follow:
From the balanced equation above,
The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.
Therefore, the formation of 3.8 moles of Fe₂O₃ will release
= (3.8 × –560.66)/2 = –1065.25 KJ of energy.
Thus, –1065.25 KJ of energy is released from the reaction.
