Answer: The for the reaction is 212 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The net reaction is
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
Therefore, the for the reaction is 212 kJ
Answer:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Iron(III) Oxide, or 159.6882 grams.
Answer:
It is always twice the value of the actual yield.
Explanation:
1. the amount of heat that it would take would be :
5.1 x 10^4 J
2. I think the substance would be : Iron
3. the amount of heat required would be :
1.13 x 10^4 kJ
Hope this helps
