Answer:
4.13 moles of Fe will be produced in the reaction
Explanation:
To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.
The reaction is:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.
We assume, the Fe₂O₃ in excess, so we propose this rule of three
3 moles of CO can produce 2 moles of Fe
Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe
A or be i cant be certain which is correct but it think its one of the lm
Water's specific heat capacity is 4200 J/Kg°C
95-28=67
72.5grams in kg is 0.0725kg
Energy = 67×0.0725×4200
Energy = 20,401.5 J or 20.4015 kJ
