The energy of the photon emitted in the given transition can be calculated using the formula E = -ΔE, where ΔE is the difference in the energies of the initial and final states of the hydrogen atom.

The binding energy of the initial state is given as -0.850 eV. The final state is not specified in the question, so we cannot directly calculate the energy of the photon. However, we can use the fact that the transition is within the hydrogen atom to determine the possible final states.
In hydrogen, the energy levels are given by the equation E = -13.6/n^2 eV, where n is the principal quantum number (1, 2, 3, etc.). The initial state must have n > 1, since the binding energy is negative. The final state can have any value of n greater than the initial state, and the transition is known as an emission line.
Assuming the final state is n = 2, the energy difference is ΔE = (-13.6/2^2) - (-0.850) = 10.85 eV. Therefore, the energy of the emitted photon is E = -ΔE = -10.85 eV. This value corresponds to a photon with a wavelength of about 114 nm, which lies in the ultraviolet range of the electromagnetic spectrum.
In conclusion, the energy of the photon emitted in the transition of a hydrogen atom with a binding energy of -0.850 eV to a final state with n=2 is -10.85 eV, which corresponds to a photon with a wavelength of about 114 nm.

Answer:

About 5.8 trillion miles is equal to 1 light year

so (5,878,600,000,000 miles)*(1.21 light-years) = 7,113,106,000,000 miles

To obtain a 1.75 M \(H_2SO_4\) solution, 75.0 ml of the 10.0 M \(H_2SO_4\) solution should be diluted to a final volume of 428.6 ml.

To calculate the volume of the 10.0 M \(H_2SO_4\) solution that needs to be diluted to obtain a 1.75 M solution, we can use the formula for dilution:

\(C_1V_1 = C_2V_2\)

where \(C_1\) is the initial concentration, \(V_1\) is the initial volume, \(C_2\) is the final concentration, and \(V_2\) is the final volume.

We know that the initial volume (\(V_1\)) is 75.0 ml, the initial concentration (\(C_1\)) is 10.0 M, and the final concentration (\(C_2\)) is 1.75 M. We can rearrange the formula to solve for \(V_2\):

\($V_2 = \frac{C_1}{C_2} \times V_1$\)

Substituting the values:

\(V_2\) = (10.0 M / 1.75 M) * 75.0 ml = 428.6 ml

This can be done by adding water to the 75.0 ml of the 10.0 M solution until the total volume reaches 428.6 ml. The resulting solution will have a concentration of 1.75 M \(H_2SO_4\).

The density (g/cm3) of 48.0 g of a metal if the level of water in a graduated cylinder rises from 25.0 mL to 33.0 mL after the metal is added density will be 6.0 g/cm3. option B is correct.

The density of any substance is the division of the mass of the given substance to the volume of the given substance and its unit is centimeter cube.

where,

density = mass of substance / volume of the substance

            mass of substance = 48.0 g

            volume of substance =  33.0  - 25.0 = 8 ml

substituting the value in the formula,

density = 48.0 / 8 = 6 cm³

Therefore, density (g/cm3) of 48.0 g of a metal if the level of water in a graduated cylinder rises from 25.0 mL to 33.0 mL after the metal is added density will be 6.0 g/cm3. option B is correct.

Answer:

4.46 moles of Ethylene will produce 392.48 grams of Carbon dioxide.

Explanation:

The reaction is as follows

C2H4 + 3 O2 → 2 H2O + 2 CO2

For complete combustion of Ethylene 1 mole of ethylene gives 2 moles of Carbon dioxide.

using unitary method

1 C2H4 => 2CO2

4.46 of C2H4  => 2*4.46 CO2

                         =  8.92 CO2

No of moles  = given mass(w) /molar mass(M)

Molar mass of CO2 = 44g

8.92 = W / 44

W = 8.92 * 44

    = 392.48g

So 4.46 moles of Ethylene will produce 392.48 grams of Carbon dioxide.

4.46 moles of ethylene burns in oxygen to give 393 g of carbon dioxide and water.

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Let's consider the reaction for the combustion of ethylene.

C₂H₄ + 3 O₂ → 2 H₂O + 2 CO₂

We can calculate the mass of CO₂ formed by the combustion of 4.46 moles of C₂H₄, considering the following relationships.

4.46 mol C₂H₄ × (2 mol CO₂/1 mol C₂H₄) × (44.01 g CO₂/1 mol CO₂) = 393 g CO₂

The statement is FALSE. Non-ferrous metals can be hardened by heat treatment, although the mechanisms and processes involved may differ from ferrous metals.

Heat treatment techniques such as precipitation hardening can be used to increase the strength of non-ferrous metals. Non-ferrous metals are metals or alloys that do not include iron (or iron allotropes, such as ferrite, etc.) in significant quantities. Non-ferrous metals are employed because they have desired qualities like reduced weight (for example, aluminium), greater conductivity (for example, copper), non-magnetic characteristics, or corrosion resistance (for example, zinc), even though they are often more expensive than ferrous metals. In the iron and steel sectors, several non-ferrous materials are also employed. Bauxite, for instance, is used as a flux in blast furnaces, whereas wolframite, pyrolusite, and chromite are utilised to create ferrous alloys.

In chemistry, the empirical formula of a chemical compound is the simplest whole-number ratio of atoms present in a compound.

-----------------

Step 2

Information provided:

Composition,

50.7 % C

9.9 % H

39.4 % N

-----------------

Step 3

Assuming a 100 grams sample:

50.7 % C => 50.7 g C

9.9 % H => 9.9 g H

39.4 % N => 39.4 g N

-----------------

Step 4

The number of moles of each element is calculated as:

(Please, use your periodic table)

50.7 g C x (1 mole C/12.01 g C) = 4.22 moles C

9.9 g H x (1 mole H/1.008 g H) = 9.82 moles H

39.4 N x (1 mole N/14.00 g N) = 2.81 moles N

-----------------

Step 5

Each number in step 4 will be divided by the smallest one of the 3. It is also needed integer numbers.

4.22 moles C/2.81 moles N = 1.5

9.82 moles H/2.81 moles N = 3.5

2.81 moles N/2.81 moles N = 1

As we need integer numbers, we will multiply all these numbers by 2 as it follows:

C => 1.5 x 2 = 3

H => 3.5 x 2 = 7

N => 1 x 2 = 2

P(X < 3) = 0.676

(c) Probability of at least three insect fragments in a 4-gram sample:

P(X >= 3) = 1 - P(X < 3)

P(X >= 3) ≈ 1 - 0.676

P(X >= 3) =  0.324

(d) Probability of at least one insect fragment in a 4-gram sample:

A synthetic compound is a substance made out of numerous indistinguishable particles containing molecules from more than one compound component kept intact by substance bonds. A particle comprising of iotas of only one component is subsequently not a compound.

A pure form of matter that cannot be further broken down into simpler forms by physical procedures is called an element. A compound is a substance that is composed of two or more different elements chemically combined. In this scenario, heating the sample of matter resulted in two different forms: a liquid and a gas.

The correct statement that describes how the sun's heat reaches the poles is:

Oceans transport warm waters from the equators to the poles.

This is because the oceans act as a heat reservoir that helps to redistribute the heat from the equator to the poles.

What is Occean Current ?

An ocean current is a continuous, directed movement of seawater within the ocean. Ocean currents are driven by a variety of factors, including the rotation of the earth, prevailing winds, and differences in temperature and salinity. They can be categorized into two main types: surface currents and deep-water currents.

Surface currents are driven by wind and the rotation of the earth, and they flow in the uppermost 400 meters of the ocean. These currents are affected by the shape of the continents, the location of land masses, and the Coriolis effect, which is the apparent deflection of moving objects due to the rotation of the earth. Surface currents have a significant impact on climate and weather patterns, as they transport warm or cold water from one region to another.

The sun's heat warms the waters near the equator, which then flow toward the poles through ocean currents. As the warm water moves toward the poles, it releases heat into the atmosphere, helping to warm the air and land at the poles. This process helps to moderate the temperature differences between the equator and the poles.
