Answer:
Explanation:
You calculate the energy required to break all the bonds in the reactants.
Then you subtract the energy needed to break all the bonds in the products.
CH₃CH₂OH + 3O₂ ⟶ 2CO₂ + 3H₂O
Bonds: 5C-H 1C-C 1C-O 1O-H 3O=O 4C=O 6O-H
D/kJ·mol⁻¹: 413 347 358 467 495 799 467

Answer: The final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Explanation:
It is known that the heat capacity of ethylene is 2.145 J/g K. Hence, for 10 moles of ethylene its mass will be as follows.
No. of moles =
10 mol =
mass = 280.5 g
Now, we know that relation between heat energy, mass and specific heat is as follows.
q =
1329.63 = T - 473
T = 1802.63 K
or, =
=
Thus, we can conclude that the final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Answer:
The table feels cold because it is at a lower temperature than the students' hands, and thermal energy is being pulled into the table.
