Considering the definition of enthalpy of vaporization, the amount of heat that would be involved in condensing 15.8 g of CH₃OH is 18.8 kJ.
When a material changes phase from solid to liquid, or from liquid to gas, a certain amount of energy is involved in this phase change.
In case of phase change from liquid to gas, this amount of energy is known as enthalpy of vaporization (symbolized as ∆Hvap).
So, the enthalpy of vaporization is the amount of energy required to change a unit of mass (for example, moles or kg) of a substance from phase liquid to phase gas at constant temperature and pressure.
In this case, you know that enthalpy of vaporization is ∆Hvap = 38.0 kJ/mol.
On the other side, you want to vaporize 15.8 g of CH₃OH. Then, being the molar mass of the compound 32 [tex]\frac{g}{mole}[/tex] (that is, the amount of mass contained in one mole), the number of moles to be vaporized is:
[tex]15.8 gramsx\frac{1 mole}{32 grams} =0.49375 moles[/tex]
Then, the amount of heat that would be involved in condensing 15.8 g of CH₃OH is calculated taking into account the enthalpy of vaporization by:
0.49375 moles× 38.0 [tex]\frac{kJ}{mol}[/tex]= 18.76 kJ ≅ 18.8 kJ
Finally, the amount of heat that would be involved in condensing 15.8 g of CH₃OH is 18.8 kJ.

What is black? You may have already got an answer, but keep reading because your answer could also be incorrect. You might have the correct solution, but it might not be exactly right so you ought to take your time and keep reading this thoroughly.
You might think black is just defined as a color, but it isn't, just not the right properties to be defined as just a color. The definition of black goes deeper. Black isn't exactly defined as a color because it's the whole absence of light and shine, and also, color. Within the visible art world, black and white, sometimes are usually defined as distinct colors. This is different from the scenario of spectral colors in physics.
Black is really a color which ends up from missing or complete absorption of all visible/invisible light. It's a neutral color, without hue, like white and gray. It's often used symbolically or figuratively to represent darkness of the very darkest color because of the absence of or complete absorption of light; the other of white.
Well black represents darkness, evil, despair, and also the night/the abyss. It is the color accustomed to convey specifically/certain and jurisdiction, and when used because the opposite as white, it is a symbol of the eternal struggle between day and night, well-being and evil/hatred, and right and crime/wrong.
So in conclusion, black represents darkness, evil, and despair, it is a symbol of the eternal struggle between day and night, well-being and evil, between right and wrong. It is the color accustomed to convey specifically/certain and jurisdiction, and it is also the opposite of white. It is not just a color, it's more known as a distant color because it is without light and hue.

The entropy change can be calculated by the given formula:
Thus, the value of change in entropy for freezing process of 1 mole of liquid methanol is -18.07 J/mol.k
(Hope this helps can I pls have brainlist (crown)☺️)
For the freezing of 1 mole of liquid methanol, the change in entropy value is -18.07 J/mol.
What is entropy value?The measure of atoms' or molecules' potential arrangements is known as entropy. Entropy change for one mole of liquid methanol frozen at -97.6 degrees Celsius and one atmosphere is -18.07 J/mol.
The range of entropy is 0 to 1. Depending on the number of classes in your dataset, entropy can be greater than 1, but it still indicates a very high level of chaos. For the sake of convenience, the examples in this blog will have entropy values between 0 and 1.
The "information" a variable contains is measured by its entropy. Now, based on the surprise that this value of the bholds and the number of distinct values that are present in the variable, this amount is approximated.
Thus, it is -18.07 J/mol.

When you float an ice cube in water, you notice that 90% of it is submerged beneath the surface. Now suppose you put the same ice cube in a glass of some liquid whose density is less than that of water.
Answer:
option c
Explanation:
90% of the body is submerged in water.
Now it is immersed in an unknown liquid whose density is less than the density of water.
Buoyant force acting on the body depends on the volume immersed, density of liquid and gravity.
As the density of liquid is less than the density of water, so the buoyant force acting on the body by the unknown liquid is less than water. So it is submerged less than 90% in this liquid.
A story with multiple narrators will usually have a(n) ____________ plot.
Answer:
nonlinear
Explanation:
It has become increasingly popular in young adult novels to have
multiple narrators. Often, this is done through alternating
chapters. One chapter is told from one perspective, while the
next chapter is told from another. This can be done with either
first person or third person limited.
Multiple Narrators
This will likely mean that the plot is nonlinear in such a novel. The
reader will jump from one character and event to another (and
sometimes even see the same event twice, but from different
perspectives).
This is also sometimes called "alternating point of view".
Stories could either have a single or multiple narrator(s). Hence, stories having multiple narrators would usually have a non-linear plot.
Multiple narrators in a story means that characters in the story are numerous, hence, acts and scenes would have to be passed on to these characters from time to time. As for single narrator, this is not the case as the number of actors are very limited.Hence, because multiple narrators often hinders a story to be chronologically ordered, then it would result in a non-linear plot.

Select the two recommendations that would decrease the margin of error of the interval.
From the options given, the only option which would result on having a reduced error margin, is to increase the sample size.
Recall :
Margin of Error = Zcritical × σ/√n
Increasing the mean would have no impact on the margin of error as it is not a part of the factors which affects the margin of error value. Increasing the standard deviation, which is the Numerator will result in an increased margin of error value. By raising the confidence level, the critical value of Z will increase, hence widening the margin of error. The sample size, n being the denominator, would reduce the value of error margin.Hence, only the sample size will cause a decrease in the margin of error of the interval.

Determine the minimum mass of hydrogen gas required to produce 226 kj of heat.
By definition, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.
The reaction is as follows:
2 H₂(g) + O₂(g) → 2 H₂O(g) ΔH = - 483.5 kJ
In this reaction, you can see that 2 moles of H₂ produces 483.5 kJ of heat. But you want to release 226 kJ of heat.
So you can apply the following rule of three: if 483.5 kJ is released by 2 moles of H₂, 226 kJ of heat is released by when moles of H₂?
[tex]amount of moles of H_{2} =\frac{226 kJx2 moles }{483.5 kJ}[/tex]
amount of moles of H₂= 0.93485 moles
Molar mass is the amount of mass that a substance contains in one mole. In this case, the molar mass of H₂ is 2 [tex]\frac{g}{mole}[/tex].
So, the mass containing 0.93485 moles is calculated as:
0.93485 moles× 2 [tex]\frac{g}{mole}[/tex]= 1.8697 grams
Finally, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.

How many grams of iron (density = 7. 87 g/ml ) would occupy the same volume as 96. 4 g of aluminum (density = 2. 70 g/ml)?.
Explanation:
density = mass / volume
96.4 g of aluminum / volume = 2.7
therefore,
96.4 = 2.7 × volume
volume = 96.4 / 2.7 = 35.7037037... ml
back to iron :
7.87 = mass / 35.7037037...
mass = 7.87 × 35.7037037... = 280.9881481... g
it would be 280.9881481... g of iron in the same volume.
