Explanation:
solution:
Hydration is the addition of water; hydrogenation is the addition of hydrogen.
desire rxn: _C4H6(g) + 2 H2(g)-----> C4H10(g)___dHhy = ??
knowns:
__________C4H6 + 11/2 O2 --------> 4CO2 + 3H2O______dHox = -2540.2 kJ/mole
__________4CO2 + 5H2O -----------> C4H10 + 13/2 O2___-dHox = 2877.6 kJ/mole
___________2(1/2 O2 + H2 -------------> H2O)___________2*dHox = 2(-285.8 kJ/mole)
Basic mathematics is a prerequisite to chemistry – I just try to help you with the methodology of solving the problem
A clean energy<span> resource. </span>Nuclear energy<span> originates from the splitting of uranium atoms – a process called fission. This </span>generates<span> heat to </span>produce<span> steam, which is used by a turbine </span>generator<span> to </span>generate electricity<span>. Because </span>nuclear power<span> plants</span>do<span> not burn fuel, they </span>do<span> not </span>produce<span> greenhouse gas emissions. I hope that this helps you out, have an amazing day!!</span>
