A photon has an energy of 2.88×10^-18 J . Convert energy into eV.

Answers

Answer 1

A photon has an energy of 2.88 × 10⁻¹⁸ J. The energy into eV is 17.97 eV.

What is Photon Energy ?

The energy which is carried by a single photon is called Photon energy.

It is expressed as:

E = hf

where,

E = Photon energy

h = Planck's energy

f = Wave frequency

How to convert Joules (J) into Electron volt (eV) ?

To convert J into eV

E(eV) = E(J) × 6.241509 × 10¹⁸

         = 2.88 × 10⁻¹⁸ × 6.241509 × 10¹⁸

         = 17.97 eV

Thus from the above conclusion we can say that A photon has an energy of 2.88 × 10⁻¹⁸ J. The energy into eV is 17.97 eV.

Denise was driving east over a hill in the afternoon, shortly after a rain shower. Suddenly the sun broke through the clouds, and she saw a rainbow ahead of her. Which of the following made the rainbow possible?

Answers

Answer: A. Raindrops act like a prism and separate the white light in sunlight.

Explanation:

The reason for the formation of rainbow is option A. Raindrop acts like a prism and separate the white lite into different colors.

What is rainbow?

Rainbow is an arc of colors from a white light ray which can be formed by the separation of component colors from white light by the combination of reflection, and refraction.

White light absorbs all colors and reflect all of them. That is why a white object is seen white the mix of all colors. When the white light passes through a raindrop, it gets refracted, the refracted light then reflects from the drop and undergo one more refraction and that make the component colors  in the form a bent or arc.

Therefore, raindrop is acting like a prism to separate the white light into its component colors.  Hence, option A is correct.

The water cycle describes the movement of water on Earth. Water in oceans and lakes evaporates and turns into water vapor. This water vapor condenses and forms clouds which produce precipitation. Precipitation falls all over the Earth's surface. The water eventually comes back to the oceans through run-off. Which steps in the water cycle carry water out of an ocean and into a freshwater lake?
A. Evaporation and precipitation
B. Rivers and streams
C. Underground tunnels
D. Condensation and run-off

Answers

Answer:

c. Underground tunnels

Explanation:

Yes, water below your feet is moving all the time, but, no, if you have heard there are rivers flowing below ground, that is not true. Water moves underground downward and sideways, in great quantities, due to gravity and pressure. Eventually it emerges back to the land surface, into rivers, and into the oceans to keep the water cycle going.

Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.

The steps in the water cycle that carries water out of the ocean into a freshwater lake are rivers and streams.

The carbon and silicon have in common that they belong to the same column (family), therefore they have the same number of total electrons. So, option B is correct.

What do carbon and silicon have in common?

Carbon's closest analogue is silicon. Silicon and carbon are both tetravalent atoms that primarily form covalent (non-ionic) compounds. However, aside from the fact that both elements "can form four covalent bonds," there is surprisingly little in common between them.

Carbon has an atomic number of 6 and an electronic configuration of 2, 4. Silicon has an atomic number of 14 and an electronic configuration of 2, 8, 4. Because both elements have the same number of valence electrons, they are classified as being in the same group.

Thus, option B is correct.

A thermochemical equation indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by a triangle H does this term stand for?

Answers

Answer:

A. Enthalpy of the reaction

Explanation:

A Thermochemical equation is a balanced stoichiometric chemical equation that indicates the absorption or release of heat in addition to the reactants and products involved in the chemical reaction. The amount of energy available for conversion into heat is represented by ΔH, a this term which stands for the enthalpy change, ΔH.

The Enthalpy of Reaction or Heat of Reaction is the amount of energy in the form of heat transferred during a chemical reaction that occurs at a constant pressure. It is useful for calculating the amount of energy per mole either released or produced in a reaction, therefore is unit is kJ/mol.

In a reaction where energy is absorbed by the reactants during the formation of products, ΔH is positive. On the other hand, in a reaction where energy is released by the reactants during the formation of products, ΔH is negative.

The enthalpy change, ΔH of reactions are determined experimentally under standard conditions of 1 atm and 25 °C (298.15K). Enthalpy can be measured experimentally through the use of a calorimeter. A calorimeter is an isolated system which has a constant pressure and in which heat loss to the surroundings is minimal.

(b) in what way are carbon dioxide and orange juice similar?​

Answers

Answer:

The effects of supercritical CO2 (SC-CO2) on the microbiological, sensory (taste, odour, and colour), nutritional (vitamin C content), and physical (cloud, total acidity, pH, and °Brix) qualities of orange juice were studied. The CO2 treatment was performed in a 1 litre capacity double-walled reactor equipped with a magnetic stirring system. Freshly extracted orange juice was treated with supercritical CO2, pasteurised at 90°C, or left untreated. There were no significant differences in the sensory attributes and physical qualities between the CO2 treated juice and freshly extracted juice. The CO2 treated juice retained 88% of its vitamin C, while the pasteurised juice was notably different from the fresh juice and preserved only 57% of its vitamin C content. After 8 weeks of storage at 4°C, there was no microbial growth in the CO2 treated juice.

Find the percent composition of chromium(|||) fluoride (CrF3), which is commonly used as a dye in textiles

Answers

Answer:

%Cr = 47.71%

%F = 52.29%

Explanation:

To do this, we need the atomic weights of all the elements in the chromiun fluoride, which are the following:

Cr: 51.996 g/mol

F: 18.998 g/mol

With these atomic weights, let's calculate the molecular mass of the chromium fluoride:

MM CrF₃ = (51.996) + (18.998 * 3) = 108.99 g/mol

Now, to get the percent composition, all we have to do is divide the atomic weight of each element by the molecular mass, and then, multiply by 100%:

% = (AW / MM) * 100

Replacing with each element:

%Cr = (51.996 / 108.99) * 100

%Cr = 47.71%

%F = 100 - 47.71

%F = 52.29%
