Which one of the following correctly ranks the compounds in order of lowest enthalpy of vaporization to highest enthalpy of vaporization based only in intermolecular forces? A) CH3NH2 – CH2SH < CH2CH3 < B) CH3NH2 < CH2CH3 < CH2SH C) CH2CH3 – CH2SH < CH3NH2 D) CH2SH < CH3NH2 < CH2CH3
Answers
The correct ranking of the compounds from lowest enthalpy of vaporization to highest, based on intermolecular forces, is B) CH3NH2 < CH2CH3 < CH2SH.
The enthalpy of vaporization is the amount of energy required to vaporize a substance at its boiling point. It is an indication of the strength of intermolecular forces between molecules. The weaker the intermolecular forces, the lower the enthalpy of vaporization.
In the given compounds, CH3NH2, CH2CH3, and CH2SH, the dominant intermolecular forces are hydrogen bonding, dipole-dipole interaction, and van der Waals forces, respectively.
CH3NH2 has the strongest intermolecular forces due to the presence of a hydrogen bond between the nitrogen and hydrogen atoms.
The hydrogen bond is a strong dipole-dipole interaction between a partially positive hydrogen atom and a partially negative atom (nitrogen, in this case). Thus, CH3NH2 has the highest enthalpy of vaporization.
CH2CH3 has dipole-dipole interactions, but they are weaker than the hydrogen bonding in CH3NH2. Therefore, it has a lower enthalpy of vaporization than CH3NH2.
CH2SH has van der Waals forces between its molecules. Van der Waals forces are the weakest intermolecular forces and are caused by temporary dipoles in the molecules. Therefore, CH2SH has the lowest enthalpy of vaporization.
Thus, the correct ranking of the compounds from lowest enthalpy of vaporization to highest, based on intermolecular forces, is CH2SH < CH2CH3 < CH3NH2.

how does eating contribute to the flow of energy in a ecosystem
Answers
Answer:
Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).
-Carbon bonds in food are broken, which releases energy.
-Weathering breaks down rocks into chemicals like sulfur and nitrogen. -Consumers make food using light energy from the sun.
-Energy is absorbed as heat when plants make food
When burning 180g of glucose in the presence of 192g of oxygen, water and carbon dioxide are produced. If 108g of water is produced, how many grams of carbon dioxide are produced?
Answers
The mass of carbon dioxide in this is 264 g according to the given data.
What is molar mass?The molar mass is basically the total mass in grams of the atoms that make up a molecule per mole. Molar mass is measured in grams per mole.
Combustion is the process of burning glucose in the presence of oxygen.
The balanced reaction is
\(C_6H_1_2O_6+6O_2---- > 6CO_2+6H_2O\)
As a result, each mole of glucose requires six moles of oxygen molecules.
Glucose has a molar mass of 180g per mole.
The present moles of glucose = mass / molar mass = 180 / 180 = 1 moleThe present moles of oxygen = mass / molar mass = 192 / 32 = 6 molesAs a result, the reaction will be completed, with one mole of glucose reacting with six moles of oxygen to produce six moles of Carbon dioxide and six moles of water.
Carbon dioxide produced mass = moles X molar mass = 6 x 44 = 264 g
Thus, 264g will be the mass of the carbon dioxide produced.

Steve walks from his house 5 I'm south then turns east and walks 2 km. Then he walks 9 in North to his older sister's house. She gives him a ride to his friend Fred's house 2 km west. Find his distance
Answers
Answer:
18 km
Explanation:
To know the distance, you need to be clear in the concept of distance.
According to the physics, the distance is a measurement that refers to the fact of how much an object has move from one point to another.
In this case, we have a person named Steve and he's walking through several points.
To calculate the distance that he moved, you just need to sum all the values of distance. In this case, it's not neccesary to do calculations regarding the components of the x or y axis, because we are not talking about displacement, where it actually counts. But in this case, we just need all the covered distance that Steven walked since the beggining.
So, no more talk, let's do calculations:
D = 5 + 2 + 9 + 2 = 18 km
So the final answer would be:
Distance = 18 kmHope this helps

A refrigeration system reaches operational balance when the number of vapor molecules that condense into liquid equals the number of vapor molecules that the compressor pumps into the condenser.
a. True
b. False
Answers
In refrigeration, the refrigerant is a substance that absorbs heat from the surrounding and dissipates it to produce cooling. The correct option is a. True.
What is thermal balance?
The thermal balance in a refrigeration system is achieved when the system has reached a stable state, that is, the amount of heat absorbed by the refrigerant is equal to the heat rejected by the refrigeration system. During the compression process, the refrigerant is compressed and pumped into the condenser where it undergoes condensation, i.e., it changes from a gas to a liquid by releasing heat.
In the condenser, the refrigerant rejects the heat that it absorbed in the evaporator and releases it to the surrounding. The condensation process reduces the number of vapor molecules in the refrigerant, which leads to an increase in the number of liquid molecules.
Therefore, the number of vapor molecules that condense into liquid equals the number of vapor molecules that the compressor pumps into the condenser. This is because the compressor has to maintain a constant flow of refrigerant in the refrigeration system to achieve thermal balance.
Hence, the statement is a) true.

1.92
Explanation:
3. Determine the pH of each of the following solutions. (Hint: See Sample Problem B.) a. 1.0 x 10-2 M HCI c. 1.0 x 10-MHI b. 1.0 x 10-3 M HNO3 d. 1.0 x 10-M HB
Answers
Answer:
a. pH = 2 b. pH = 3 c. pH = 1 d. Unanswerable
Explanation:
pH = -log[H+] OR pH = -log{H3O+]
and inversely
pOH = -log[OH-]
1. Determine what substance you are working with, (acid/base)
2. Determine whether or not that acid or base is strong or weak.
a. 1.0 x 10^-2M HCl
HCl is a strong acid, therefore it will dissociate completely into H+ and Cl- with all ions going to the H+, therefore, the concentration of HCl and concentration of H+ are going to be equal, meaning we simply take the negative logarithm of the concentration of HCl and that would equal pH
pH = -log[H+]
pH = -log(1.0x10^-2)
pH = 2
b. 1.0 x 10^-3M HNO3
HNO3 like part a, is a strong acid, therefore it would simply require you to take the negative logarithm of the concentration of the compound itself, to find its pH.
pH = -log[H+]
pH = -log(1.0 x 10^-3)
pH = 3
c. 1.0 x 10^-1M HI
Like the previous parts, HI is a strong acid
pH = -log[H+]
pH = -log(0.10)
pH = 1
d. HB isn't an element, nor is it a compound so that would be unanswerable.

temperature of the water decreases from 27 C to 18 C. The specific heat
of water is 4. 18 J/gC. Calculate the heat transferred
Answers
To calculate the heat transferred, we can use the formula:
Q = m * c * ΔT
Where:
Q is the heat transferred
m is the mass of the water
c is the specific heat capacity of water
ΔT is the change in temperature
Given:
Mass of water (m) = 160 grams
Specific heat capacity of water (c) = 4.18 J/g°C
Change in temperature (ΔT) = 27°C - 18°C = 9°C
Substituting the values into the formula:
Q = 160 g * 4.18 J/g°C * 9°C
Calculating the expression:
Q = 6028.8 J
Therefore, the heat transferred is 6028.8 Joules.
