Answer:
Sorry but I do not the answer to help you but I will advise you to look in internet for better answer and secondly I think your cheating while doing paper
Answer:
(a) The system does work on the surroundings.
(b) The surroundings do work on the system.
(c) The system does work on the surroundings.
(d) No work is done.
Explanation:
The work (W) done in a chemical reaction can be calculated using the following expression:
W = -R.T.Δn(g)
where,
R is the ideal gas constant
T is the absolute temperature
Δn(g) is the difference between the gaseous moles of products and the gaseous moles of reactants
R and T are always positive.
- If Δn(g) > 0, W < 0, which means that the system does work on the surroundings.
- If Δn(g) < 0, W > 0, which means that the surroundings do work on the system.
- If Δn(g) = 0, W = 0, which means that no work is done.
<em>(a) Hg(l) ⇒ Hg(g)</em>
Δn(g) = 1 - 0 = 1. W < 0. The system does work on the surroundings.
<em>(b) 3 O₂(g) ⇒ 2 O₃(g)
</em>
Δn(g) = 2 - 3 = -1. W > 0. The surroundings do work on the system.
<em>(c) CuSO₄.5H₂O(s) ⇒ CuSO₄(s) + 5H₅O(g)
</em>
Δn(g) = 5 - 0 = 5. W < 0. The system does work on the surroundings.
<em>(d) H₂(g) + F₂(g) ⇒ 2 HF(g)</em>
Δn(g) = 2 - 2 = 0. W = 0. No work is done.
When it has been disproven
<span>The answer to this question would be: B.They are different.
A compound will have different characteristics from their element. </span>The interaction of different elements in a compound makes it so. They might have similar or opposite characteristic but it didn't always happen so those answers are not best.
all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
