how is sonoluminescence similar to what we see in fireworks?​

Answers

Answer 1

Answer:

Explanation:

Sonoluminescence is a phenomenon in which small gas bubbles burst to produce light when intense sound wave is introduced. Thus, it can be said that sound energy is converted to light energy here. This is similar to the process of how fire crackers work except that sonoluminescence occurs in a liquid medium while firecrackers work in solid media. In firecrackers, when the tip is lit with fire, the initial explosion is caused by the expansion of some nitrogen and carbon present in some constituent compounds, this explosion produces heat which causes some other constituent chemicals in the firecracker to quickly react and produce light. Thus, this can also be said to convert sound energy to light energy and are thus similar to what occurs in sonoluminescence.

Answer:

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets—Mercury, Venus, Earth and Mars—are terrestrial planets.

Conglomerate is closely related to sandstone and displays many of the same types of sedimentary structures. Sandstone is a notably popular building material, used for things like flagstones and tile.

Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.

Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.

Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.

These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity

Answers

Answer:

The final velocity of the motorcycle is 64.7 m/s

Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation

Explanation:

Using the equation of motion that contains all the given values in the question: v² = u² + 2as

where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance

v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m

v² = 0² + 2 * 4.55 * 460

v² = 4186

take square root of both sides

v = 64.7 m/s

Therefore, the final velocity of the motorcycle is 64.7 m/s

What is the enthaply of dissolution? ​

Answers

Answer:

The enthalpy change of solution refers to the amount of heat that is released or absorbed during the dissolving process (at constant pressure).

Explanation:

The enthalpy of solution, enthalpy of dissolution, or heat of solution is the enthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution.
The enthalpy of solution is most often expressed in kJ/mol at constant temperature. The energy change can be regarded as being made of three parts, the endothermic breaking of bonds within the solute and within the solvent, and the formation of attractions between the solute and the solvent. An ideal solution has a null enthalpy of mixing. For a non-ideal solution it is an excess molar quantity.

Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane​

Answers

Answer:

C. the carbons in ethene are linked by double bonds

Explanation:

The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.

In single bonds afforded with the ethane compound, there is free rotation.

The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

The sedimentary rocks that are formed from physical/chemical process within the earth are given the general name of chemical precipitation.

What do you mean by the chemical precipitation ?

Chemical precipitation is the process of turning a liquid into a solid by either making the liquid insoluble or making it very saturated.

Chemical precipitation, which starts when water moving through rock dissolves part of the minerals, creates chemical sedimentary rocks. When the water evaporates, the minerals are finally redeposited or precipitated after being moved away from their source.

A chemical compound that develops when the solution it was dissolved in, often water, evaporates and leaves the compound behind is known as a chemical precipitate.

Thus,Chemical precipitation is the process that gives rise to chemical sedimentary rocks including limestone, halite, and flint.

A student cut out a spiral shape from a piece of tissue paper and hung it from a string over a light bulb. Nothing happened. Next the student turned on the light. After a few seconds, the spiral began to turn above the light. Which of these best explains what happened?​

Answers

Answer:

See explanation

Explanation:

Initially, when the paper is hung over the light bulb, we observe that nothing happens at all.

As time goes on, air surrounding the lamp begins to heat up. Remember that hot air is lighter and less dense than cold air.  Air surrounding the lamp which has now become hotter and less dense rises and pushes on the spiral. This causes the spiral to begin to spin.

Answer:

A)  0.0499

Explanation:

According to the mole concept, 2.80 g of calcium oxide sample  has 0.0499 moles.

What is mole concept?

According to the mole concept,mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

As per the formula for number of moles, which is mass/molar mass

number of moles of calcium oxide is:2.80/56.08=0.0499 moles.

Hence, 2.80 g sample of calcium oxide has 0.0499 moles.
