THE REACTION IS COMBINATION REACTION!
The question is incomplete , complete question is:
Hydrogen, a potential future fuel, can be produced from carbon (from coal) and steam by the following reaction:

Note that the average bond energy for the breaking of a bond in CO2 is 799 kJ/mol. Use average bond energies to calculate ΔH of reaction for this reaction.
Answer:
The ΔH of the reaction is -626 kJ/mol.
Explanation:

We are given with:



ΔH = (Energies required to break bonds on reactant side) - (Energies released on formation of bonds on product side)



The ΔH of the reaction is -626 kJ/mol.
Answer:
<h3>The answer is 9.0 kg/L</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 1.8 kg
volume = 0.2 L
We have

We have the final answer as
<h3>9.0 kg/L</h3>
Hope this helps you
