Answer:

A) H₂O at 120°C

Explanation:

It is possible to think the higher temperature, the greatest degree of disorder. That is because with a high temperature, vibrations of molecules increases.

In general, at low temperatures, the molecules are in solid state (The lowest degree of disorder), increasing its temperature, molecules becomes in liquids, and, with more temperature, are gases (The greatest degree of disorder).

Thus, the sample that has the greatest degree of disorder is:

<h3>A) H₂O at 120°C</h3>

Identify the change in state that does not have an increase in entropy. a. Water evaporating b. Dry ice subliming c. Water boili
jarptica [38.1K]

Answer:

E. Water Freezing

Explanation:

Entropy refers to the degree of disorderliness of a system.  

A. Water Evaporating: There is an increase in entropy, this is because the phase change is from liquid to gas. Gas particles are more disordered than liquid.

B. Dry Ice sublimating: Sublimating refers to a phase change from solid to gas. This is an increase in entropy, this is because the gas particles are more disordered than solid particles

C. Water Boiling: The phase change is from liquid to gaseous state. There is an increase in entropy. Gas particles are more disordered than liquid.

D. Ice melting: The phase change is from solid to liquid state. There is an increase in entropy. Liquid particles are more disordered than that of solid.

E. Water Freezing: The phase change is from liquid to solid state. There is a decrease in entropy. solid particles are less disordered than those of liquid.

The volume of the earth is approximately 1.08326x10 to the 12th power km to the 3rd power. How many liters is this
mafiozo [28]

Here, we are required to determine the volume of the earth which is 1.08326 × 10¹² km³ in liters.

<em>The volume of the earth is approximately</em>,

, 1.08326 × 10²⁴ liters

By conversion factors;

  • <em>1dm³ = 1liter</em>
  • However; <em>1km = 10000dm = 10⁴ </em><em>dm</em>
  • Therefore, 1km³ = (10⁴)³ dm³.

Consequently, 1km³ = 10¹²dm³ = 10¹²liters.

The conversion factor from 1km³ to liters is therefore, c.f = 10¹²liters/km³

Therefore, the volume of the earth which is approximately, 1.08326 × 10¹² km³ can be expressed in liters as;

<em>1.08326 × 10¹² km³ × 10¹²liters/km³ </em>

The volume of the earth is approximately,

1.08326 × 10²⁴ liters.

Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H
GalinKa [24]
The balanced chemical reaction is:

N2 + 3H2 = 2NH3

We are given the amount of hydrogen gas to be used in the reaction. This will be the starting point of the calculations.

24.0 mol H2 (2 mol NH3 / 3 mol H2 ) = 16 mol NH3

Therefore, ammonia produced from the reaction given is 16 moles.
