The energy released during a nuclear reaction in a power plant is directly used to __________

A. create electric current
B. fuse hydrogen into helium
C. heat water
D. energize control rods

Answers

Answer 1

Final answer:

In a nuclear power plant, the energy released from the fission of uranium-235 is used to heat water, producing steam that drives turbines to generate electricity.

Explanation:

The energy released during a nuclear reaction in a power plant is directly used to heat water. In a nuclear power plant, a nuclear reactor uses the energy produced in the fission of uranium-235 to produce electricity. The fission reaction generates heat, which is transferred to water surrounding the fuel rods causing it to turn into steam. This steam then drives turbines connected to generators, thereby generating electric current. Control rods made out of materials like boron, cadmium, or hafnium, which absorb neutrons, are used to control the rate of the fission reaction, but they are not directly energized by the reaction.

436 Kelvin = 162.85 Celsius. To convert from Kelvin to Celsius you can use the folowing formula:

[°C] = [K] − 273.15.

Answer : The correct option is, [tex]163^oC[/tex]

Explanation :

The conversion used for the temperature from Kelvin to degree Celsius is:

[tex]K=273+^oC[/tex]

where,

K = temperature in Kelvin = 436 K

[tex]^oC[/tex] = temperature in degree Celsius = ?

Now put the value in the above conversion, we get the temperature in degree Celsius.

[tex]436=273+^oC[/tex]

[tex]^oC=436-273[/tex]

[tex]^oC=163[/tex]

Therefore, the temperature in degree Celsius is, [tex]163^oC[/tex]

if the waste you have contains 100.0 grams of silver nitrate, how many mols of silver nitrate is this

Answers

Final answer:

To find the number of moles of silver nitrate, divide the mass by the molar mass.

Explanation:

To determine the number of moles of silver nitrate in a given mass, we need to use the molar mass of silver nitrate. The molar mass of silver nitrate (AgNO3) is 169.88 g/mol.

Given that the waste contains 100.0 grams of silver nitrate, we divide the mass by the molar mass to find the number of moles:

Number of moles = Mass (g) / Molar mass (g/mol)

Number of moles = 100.0 g / 169.88 g/mol = 0.589 mol

1. Given 100.0 grams of silver nitrate, we calculate it to be approximately 0.588 moles of silver nitrate.

2. According to the balanced chemical equation with copper, 0.294 moles of copper are needed to completely react with the silver nitrate. This ensures the reaction proceeds to completion.

To determine the number of moles of silver nitrate (AgNO₃) from the given mass, we use its molar mass:

Determine the molar mass of AgNO₃: 169.88 g/mol.Calculate the moles of silver nitrate:
Moles of AgNO₃ = mass / molar mass = 100.0 g / 169.88 g/mol ≈ 0.588 mol.

Next, we need to determine how many moles of copper (Cu) are needed to react completely with the silver nitrate.

The balanced chemical reaction between these two substances is:

2AgNO₃(aq) + Cu(s) → Cu(NO₃)₂ (aq) + 2Ag(s)

From the balanced equation, we see that 1 mole of Cu reacts with 2 moles of AgNO₃. Therefore, we use the stoichiometric ratio to find the required moles of copper:

Moles of Cu = 0.588 mol AgNO₃ * (1 mole Cu / 2 moles AgNO3) = 0.294 mol Cu

Correct question is: Answer the following :

1. If the waste you have contains 100.0 grams of silver nitrate, how many moles of silver nitrate is this? (Use the molar mass of the silver nitrate from above)
2. If you found that the waste contains 100.0 grams of silver nitrate, how many moles of copper would you need to completely react with all of the silver nitrate?

A certain shade of blue has a frequency of 7.03 × 1014 Hz. What is the energy of exactly one photon of this light?

Answers

4.66 x 10^-19 Joules The energy of a photon is E=hf Where E = Energy h = Planck's constant (6.62607004Ă—10â’34 J s) f = frequency of photon. So plug in the known values E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s E = 4.65812724x10^-19 J Since we only have 3 significant figures, the rounded result is E = 4.66x10^-19 J

The energy of one photon of light with a frequency of 7.03 × 1014 Hz is approximately 4.65618 × 10-19 Joules. This is obtained using Planck's equation, E = hf, where E is the energy, h is Planck's constant and f is the frequency of the light.

Explanation:

The subject of this question is Physics. The student wants to know the energy of exactly one photon of light that has a frequency of 7.03 × 1014 Hz. We can use Planck's equation which relates the energy of photon, its frequency and Planck's constant (h = 6.626 × 10-34 J.s).

So, the energy (E) of the photon is given by the formula E = hf. Substituting the frequency (f = 7.03 × 1014 Hz) and Planck's constant into the formula gives E = (6.626 × 10-34 J.s)(7.03 × 1014 Hz) which gives approximately 4.65618 × 10-19 Joules. This is the energy of one photon of light with a frequency of 7.03 × 1014 Hz.

A metal M is converted to the metal sulfate M2(SO4)3. then a soultion of the metal sulfate was treated with calcium chloride to give calcium sulfate perciptate.If 1.2 g of the metal gave 5.451 g calcium sulfate what is the identity of metal M?
M2(SO4)3(aq)+3CaCl2(aq) ----->
2MCl3(aq)+3CaSO4(s)

Answers

1) From the chemical equation you obtaing the theoretical molar ratios:

2 mol of M : 3 mol of CaSO4

2) Convert 5.451 g of CaSO4 into number of moles

number of moles = mass in grams / molar mass

molar mass 0f CaSO4 = 136.14g/mol

=> number of moles of CaSO4 = 5.451 g / 136.14 g/mol = 0.0400 mol

3) Make a proportion with the unknown, 0.0400 mol and the theoretical molar ratio:

x / 0.0400 mol of CaSO4 = 2 mol of M / 3 mol of CaSO4

=> x = 0.400 * 2 / 3 mol of M = 0.02667 mol of M

4) Use the mass of 1.2 g and the number of moles to obtain the molar mass of M

molar mass = mass in grams / number of moles

=> molar mass = 1.2 g / 0.02667 moles = 45 g/mol

5) Use a periodic table to find the molar masses of different metals.

Scandium atomic mass is 45 g/mol, so the metal is Scandium.
