What is the enthalpy for reaction 1 reversed? reaction 1 reversed: 2co2 + 3h2o→c2h5oh + 3o2 express your answer numerically in k
Rama09 [41]

Answer: The enthalpy of the given reaction is 1234.8kJ/mol.

Explanation: Enthalpy change of the reaction is the amount of heat released or absorbed in a given chemical reaction.

Mathematically,

\Delta H_{rxn}=\Delta H_f_{(products)}-\Delta H_f_{(reactants)}

For the given reaction:

2CO_2(g)+3H_2O(g)\rightarrow C_2H_5OH(l)+3O_2(g)

H_f_{(CO_2)}=-393.5kJ/mol

H_f_{(H_2O)}=-241.8kJ/mol

H_f_{(C_2H_5OH)}=-277.6kJ/mol

H_f_{(O_2)}=0kJ/mol

\Delta H_{rxn}=\Delta H_f_{(C_2H_5OH)}+3\Delta H_f_{(O_2)}-[2\Delta H_f_{(CO_2)}+3\Delta H_f_{(H_2O)}]

Putting values in above equation, we get:

\Delta H_{rxn}=[-277.6+3(0)]-[2(-393.5)+3(-241.8)]kJ/mol

\Delta H_{rxn}=1234.8kJ/mol

The combustion of 1 mol ch4 releases 803 kj of energy. how much energy is produced from the combustion of 5.00 mol ch4.
Annette [7]

Answer : The energy produced from the combustion of 5 mole CH_4 is 4015KJ

Solution : Given,

Released energy = 803 KJ

The balanced combustion reaction is,

CH_4+2O_2\rightarrow CO_2+2H_2O

As per the question,

1 mole of CH_4 releases energy = 803 KJ

5 mole of CH_4 produced energy = \frac{5mole}{1mole}\times 803KJ=4015KJ

Therefore, the energy produced from the combustion of 5 mole CH_4 is 4015KJ

How can you turn mechanical energy into electrical energy
Ghella [55]

Answer:

In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.

Explanation:

Hope this helps!
