Answer: The answer is elastic potential energy

Explanation: Potential energy is stored energy if something is elastic that means the shape or form of an object is being compressed from its original form. Like elastic girl from the incredibles lol. but anyways if you compare somehting to a rubber band it has elastic potential energy Thus the answer is D.

Hope this helps :).

When you bend, stretch, or compress an object from its natural shape, it stores Elastic potential energy.

Elastic energy is the mechanical potential energy held in a material's or a physical system's configuration as it is subjected to elastic deformation as a result of work being done on it. Elastic energy is created when objects are momentarily crushed, stretched, or otherwise deformed.

Because it is stored in the bonds between atoms of an object or substance when it is momentarily stressed, elastic energy is a type of potential energy. The object may have been stretched or compressed, causing this stress.

An object's shape may change as a result of a force operating on it. If stretched or compressed, elastic things can store elastic potential energy. This occurs, for instance, when a spring is stretched or a catapult is utilized.

Thus, option D is correct.

Sucrose, also known as table sugar, has a total of 16 stereocenters.

Sucrose is a disaccharide made up of glucose and fructose units, which are joined by a glycosidic bond. Each glucose and fructose unit has four stereocenters, making a total of 8 stereocenters in each unit.

Therefore, sucrose has a total of 16 stereocenters.

It is important to note that sucrose does not exhibit any optical activity, despite the presence of multiple stereocenters, because the molecule has a plane of symmetry that bisects the glycosidic bond, which leads to the cancellation of the optical activity of the stereocenters.

The permitted values of j for a p electron are 1/2 and 3/2 and the permitted values of j for an h electron are 9/2 and 11/2.

(a) For a p electron:
The azimuthal quantum number (l) for a p electron is 1. To calculate the permitted values of j, we use the formula:
j = l ± 1/2
So for a p electron, the permitted values of j will be:
j = 1 + 1/2 = 3/2
j = 1 - 1/2 = 1/2
Therefore, the permitted values of j for a p electron are 1/2 and 3/2.

(b) For an h electron:
The azimuthal quantum number (l) for an h electron is 5. To calculate the permitted values of j, we use the same formula:
j = l ± 1/2
So for an h electron, the permitted values of j will be:
j = 5 + 1/2 = 11/2
j = 5 - 1/2 = 9/2
Therefore, the permitted values of j for an h electron are 9/2 and 11/2.

15.838mL of a 13.9 m hno3 stock solution must be used to prepare 350.0 ml of a solution that is 0.629 m hno3 from Oswald's Dilution law

What is Oswald's dilution law ?

The following equation can be used to relate the concentrations and volumes before and after a dilution: M1V1 = M2V2, where M1 and V1 are the volume and molarity of the original concentrated solution, respectively, and M2 and V2 are those of the final diluted solution, respectively. According to Ostwald's dilution law, "For a weak electrolyte, the degree of dissociation is directly proportional to the square root of the volume holding one mole of the solute or inversely proportional to the square root of the molar concentration." Ka=a2C/ is its mathematical formula (1-a).

S1 V1 = S2 V2

S1 = 350*0.629/13.9 = 15.838 mL

To find the volume of ethyl alcohol required, we can use the formula:

Volume = Mass / Density

Given that the mass of ethyl alcohol required is 65.3 g and the density of ethyl alcohol is 0.790 g/cm3, we can substitute these values into the formula to find the volume.

Volume = 65.3 g / 0.790 g/cm3

To simplify the units, we can convert the volume from cm3 to mL by using the conversion factor: 1 cm3 = 1 mL.

Volume = (65.3 g / 0.790 g/cm3) * (1 cm3 / 1 mL)

Calculating the expression within the parentheses gives:

Volume = 82.78 cm3 / 1 mL

Therefore, the volume of ethyl alcohol required is 82.78 mL.

Note: It is important to pay attention to the significant figures in the given values and carry them through the calculations to maintain accuracy in the final result.

It is true that the formation of a star occurs when nuclear fusion begins to fuse light elements into heavier ones;

The distance to the nearest stars can be determined by parallax, the apparent shift of a start against background stars observed as the earth moves along its orbit. (Option B)

Based on the accompanying H-R Diagram, the type of start that has the greatest temperature is the blue giants (Option C)

Two hydrogen atoms come together in a nuclear fusion reaction to produce Helium Gas. (Option A).

Hubble's law, which essentially states that the velocity of a galaxy (or, as it is commonly plotted, its redshift) is precisely proportionate to its distance, also reveals crucial information about the condition of the universe. There should be no relationship between distance and velocity if the cosmos is static and unchanging.

the reported molar concentration of the sodium hydroxide solution will be too high when is used for the standardization of the naoh solution.

The term "standardization" in scientific or analytical chemistry means the process of determining standards or concentrations of a particular substance.

One of the benefits of standardization, and the most important one, is that you get results with minimal error.

.A standard solution has an accurately known concentration and for this experiment sodium hydroxide was standardized with a primary standard acid, potassium hydrogen phthalate. A primary standard could be any pure chemical that can be used as the initiation of a quantitative analysis.

If the khp is only 90% pure, the real mass of the acid will be less than weighed doing less the real moles of potassium hydrogen phthalate. Thus, in titration, volume of NaOH will be less than real volume and reported molar concentration will be too high.

Explanation:

After 17,145 years (three half-lives), only 2.5 grams of half-life of carbon-14 will be left in the animal bone

The half-life of carbon-14 is 5,715 years, which means that every 5,715 years, the amount of carbon-14 in a sample will decrease by half. After three half-lives (17,145 years), the amount of carbon-14 remaining in the sample can be calculated using the following formula:

final amount = initial amount x (1/2)^n

where n is the number of half-lives that have elapsed.

In this case, the initial amount of carbon-14 is 20.0 grams, and n is 3 (since 17,145 years is three half-lives of carbon-14). So, we can plug in these values and solve for the final amount:

final amount = 20.0 grams x (1/2)^3

final amount = 20.0 grams x 0.125

final amount = 2.5 grams.

The N - H and the C- O  and the C- N bonds in indigo dye are polar on nature.

Indigo is a blue dye that is derived from the leaves of certain plants. The chemical structure of indigo consists of two benzene rings connected by a nitrogen atom. The molecule has several polar bonds due to the electronegativity differences between the atoms.

The polar bonds in indigo include:

The nitrogen-carbon bonds: The nitrogen atom in the middle of the molecule is connected to two carbon atoms, one in each benzene ring. Nitrogen is more electronegative than carbon, so the nitrogen-carbon bonds are polar.

The carbon-oxygen bonds: Indigo has two oxygen atoms that are double bonded to carbon atoms in the benzene rings. Oxygen is more electronegative than carbon, so the carbon-oxygen bonds are also polar.
