What happens to energy during the formation of a solution?

Answers

Answer 1

Answer:

The study of chemicals and bonds is called chemistry.

The correct answer is absorbed or released.

What is energy?

Energy is defined as the physical property which can be transferred from one body to another.
There are various types of energy present. A few examples are as follows:-
Heat energy, wind energy, light energy, etc.

Depending on the requirement of the solution, the compound can release energy to make a bond or can release energy to break the bond from the surrounding.

Hence, the correct answer is absorbed or released.

Answer 2

Answer: As the solute dissolves in the solvent,energy is absorbed and used to separate and break apart molecules. Once a solution is formed, this energyis released, increasing the temperature of the solution. ... The solution is saturated if it contains just enough of the solute that the solvent can hold.

if 1200 j of heat were absorbed by a 25 g block of iron, by how much would the temperature of the iron increase?

Answers

m = mass of the block of iron = 25 g

Q = heat absorbed by the block of iron = 1200 J

ΔT = increase in the temperature of iron due to heat absorbed = ?

c = specific heat of block of iron = 0.450 J/(g C)

Heat absorbed by the block of iron is given as

Q = m c ΔT

inserting the values in the above formula

1200 = 25 (0.450) ΔT

1200 = (11.25) ΔT

ΔT = 1200/11.25

ΔT = 106.67 C

What effect does the presence of dissolved sodium fluoride have on the dissociation equilibrium of hydrofluoric acid? (select all three that apply)...The percent dissociation of HF is reduced by the presence of dissolved NaF.
THe pH of the solution containing NaF and HF would be higher than that of a solution of HF only.
The presence of NaF drives the reaction towards the HF side to reach equilibrium.
The concentration of H+ is higher in an HF solution containing NaF.
The pH of the solution containing NaF and HF would be lower than that of a solution of HF only.
The presence of the dissolved NaF does not affect the HF equilibrium reaction nor the equilibrium concentrations.

Answers

The correct answer for the question that is being presented above is this one: "The pH of the solution containing NaF and HF would be lower than that of a solution of HF only.; THe pH of the solution containing NaF and HF would be higher than that of a solution of HF only."

The shape of a molecule is tetrahedral. How many lone pairs are most likely on the central atom?zero
two
three
four

Answers

Answer: Zero lone pairs on the central atom.

Explanation:

Lone pairs and bond pairs together decides the geometry of the molecule.
Bond pairs together decides the shape of the molecule.

The molecule is with with tetrahedral shape which means that molecule has a tetrahedral geometry.

The value of number of electrons around the central atom with tetrahedral geometry according to VESPR theory is '4'. Which means that electrons around the central atom are 4.

Since, the molecule is in tetrahedral shape which means four bonds are pointing in direction towards the four vertices of tetrahedral which means their are zero lone pair present on the central atom.

The number of lone pairs that are most likely found on the central atom is zero. There are no lone pairs found on the central atom.

The questions refer to the following graphs of mechanical waves. A
B
C

The wave with the longest wavelength is (A,B,C). The wave with the smallest amplitude is (A,B,C). The wave with the most energy is (A,B,C).

Answers

A is the wave with the longest wavelength. The graph clearly shows this since wave A has a larger wavelength than waves B and C. Wave A has the longest wavelength when compared to the other two waves.

What is the C wave ?

C is the wave with the least amplitude. The graph shows this since wave C has a significantly lesser amplitude than waves A and B. Wave C has the least amplitude when compared to the other two waves. B is the most energetic wave.

The graph shows this because wave B has a larger amplitude than waves A and C. Wave B has the greatest amplitude when compared to the other two has the more energy in comparison to the two.

The longest wavelength wave has the lowest frequency and the lowest energy. A wave's wavelength is inversely related to its frequency, which implies that as the wavelength grows, so does the frequency. Because energy is proportional to frequency, the wave with the longest wavelength has the least energy.

The wave with the smallest amplitude has the least amount of energy. The largest displacement of a wave from its equilibrium position is referred to as its amplitude. The energy of a wave is exactly proportional to its amplitude, therefore as the amplitude falls, so does the energy.
