I believe the correct answer would be that t<span>he change in enthalpy can be found by adding the enthalpies of the individual thermochemical reactions of a chemical reaction.</span> In Hess' Law, enthalpy is independent of the mechanism of the reaction. The enthalpy should be the sum of all the changes in the reaction.
Answer:
-248.425 kJ/mol
Explanation:
This question can be done by simply taking the ratios:
Since the given the heat change for 1.00 mol of 
is -373.7 KJ/mol. Let us consider the required Heat Exchange at 0.631 mol of
We can write:
KJ/mol
Answer:
2Al2O3 (l) ---> 4Al (l) + 3O2 (g)
Explanation:
The reaction is the electrolysis of aluminium oxide. It decomposes aluminium oxide (Al2O3) into aluminium metal (Al) and Oxygen (O2). In this process, aluminium oxide is molten (liquid state) so that ions can move to complete the electricity circuit.
Al2O3 (l) ---> Al (l) + O2 (g)
Balance the equation:
2Al2O3 (l) ---> 4Al (l) + 3O2 (g)
the hybridization is probably sp2. it will have 1pi bond. There is a double bond between C and O atoms and that double bond consists of 1 pi bond and 1 sigma bond.
Answer
Sounds travel slowest in gasses so it would be air
