Which chemical in the atmosphere of Titan (a moon of Saturn) plays the same role that water plays on the Earth by producing "rai
ololo11 [35]

Answer:

Methane (CH₄)

Explanation:

Titan refers to the largest moon of the planet Saturn, comprising a very dense atmosphere. This moon is primarily comprised of nitrogen gas, which is similar to the conditions in earth. It is extremely cold having a temperature of about ₋180°C, as a result of which it is difficult for the liquid water to exist.

Acid rain is a type of precipitation that occurs in the earth and it results in the release of a certain amount of methane gas (CH₄). Similarly, there also occurs precipitation in Titan but it releases CH₄ instead of water.  This methane is responsible for the increasing amount of temperature.

Thus, methane is a chemical that is present int the Titan's atmosphere, and it plays a similar role as in earth, the water plays by forming snow, rain, and ice.

When comparing propionic acid (CH3CH2COOH) and sodium propionate (CH3CH2COONa), the one that is more soluble in water is When co
vova2212 [387]

Answer:

When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate.

When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose

When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid

Explanation:

When comparing propionic acid (CH₃CH₂COOH) and sodium propionate (CH₃CH₂COONa), the one that is more soluble in water sodium propionate. Because always a salt is more soluble in water than its acid (Solubility of propionic acid is 0,37g/mL and of sodium propionate is 1g/mL).

When comparing cyclohexane (C6H12) and glucose (C6H12O6), the one that is more soluble in water is glucose because cyclohexane is made from petroleum and its polarity is very low (cyclohexane is insoluble in water and solubility of glucose is 0,91g/mL).

When comparing hydrochloric acid (HCl) and ethyl chloride (CH3CH2Cl), the one that is more soluble in water is hydrochloric acid because an acid has a medium-high solubility in water but, again, an alkane derived from petroleum has very low solubility in water (hydrochloric acid has a solubility of 0,823g/mL and ethyl chloride is insoluble in water).

I hope it helps!

Answer:

B, C, F. and H

Explanation:

<em>The correct answer would be B, C, F, and H.</em>

According to the kinetic theory, the kinetic energy of molecules of a substance is directly proportional to the temperature of the substance.

<u>The intermolecular forces holding the molecules in a solid together become weaker as the temperature of the solid increases along with the kinetic energy. The molecules vibrate and further apart, leading to the melting of the solid.</u>

Calculate the heat released when ethanol is cooled from 400K to 100K. The boiling point of ethanol is 351 K and the melting poin
Valentin [98]
The total heat of a process is the sum of all the heat involved in the process. So, the total heat is the sum of all sensible and latent heat in the whole process. For this case, the flow of the release of heat is,

sensible heat from 400 K to the boiling point (351 K) ---> latent heat due to condensation ------> sensible heat from 351 K to melting point (159 K) -----> latent heat due to freezing --------> sensible heat from 159 K to 100 K

Total heat released =  87.53 J/(mol•K)<span> (400 K - 351 K) + </span><span>38560 J/mol + </span><span>112.4 J/(mol•K) ( 351 K - 159 K ) + </span>4900 J/mol + 111.46J / (mol•K) ( 159 K - 100 K) = 75905.91 J / mol
