Answer:

At one atmosphere and twenty-five degrees Celsius, could you turn it into a liquid by cooling it down? Um, and the key here is that the triple point eyes that minus fifty six point six degrees Celsius and it's at five point eleven ATMs. So at one atmospheric pressure, there's no way that you're ever going to reach the liquid days. So the first part of this question is the answer The answer to the first part of a question is no. How could you instead make the liquid at twenty-five degrees Celsius? Well, the critical point is at thirty-one point one degrees Celsius. So you know, if you're twenty-five, if you increase the pressure instead, you will briefly by it, be able to form a liquid. And if you continue Teo, you know, increase the pressure eventually form a salad, so increasing the pressure is the second part. If you increase the pressure of co two thirty-seven degrees Celsius, will you ever liquefy? No. Because then, if you're above thirty-one point one degrees Celsius in temperature. You'LL never be able to actually form the liquid. Instead, you'LL only is able Teo obtain supercritical co too, which is really cool thing. You know, they used supercritical sio tu tio decaffeinated coffee without, you know, adding a solvent that you'LL be able to taste, which is really cool. But no, you can't liquefy so two above thirty-one degrees Celsius or below five-point eleven atmospheric pressures anyway, that's how I answer this question. Hope this helped :)

Predict the sign of the entropy change, ΔS, for the following processes. Explain the reason for each of the predictions.
Nastasia [14]

The sign of the entropy change, ΔS, for the following processes include:

  • I2 (s) + ½ Cl2 (g) ← → ICl (g) - positive
  • 3 Ag (s) + 4 HNO3 (aq) → 3AgNO3 (aq) + NO (g) + 2 H2O (l) - positive
  • Cl2 (g) → Cl2 (l) - negative
  • C5H12 (g) + 8 O2 (g) → 5 CO2 (g) + 6 H2O (l) - negative

What is Entropy?

This is referred to the degree of randomness or disorderliness of a system and is denoted as S.

Entropy change is usually positive when solid or liquid reactant is converted into gas product and vice versa.

The formula of ammonium fluoride is NH4F.

Explanation:

1 The atoms in each ion are bonded together covalently to form a single unit.

Wrong!

⇒ The atoms in an ion compound are linked together by an ionic bond.

2 The charge is distributed over the entire ion.

Wrong!

Ions have taken in or given up electrons. This happens in the atomic shell.

3 The formula of ammonium fluoride is NH4F.

Right!

4 The formula of potassium sulfate is K2SO

Wrong!
