Maru [420]2 years ago
4 0

[Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.

<h3>What is telleurium?</h3>

Tellurium is a noble gas element that is non-reactive in nature due to complete outermost shell. It has atomic number of 52 which means that it has 52 number of electrons.

So we can conclude that [Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.

What is the wavelength of a photon with an energy of 3.38 x 10-19 J?
irina1246 [14]

Answer:

C. 588 nm

Explanation:

Given parameters:

Energy of the photon  = 3.38 x 10⁻¹⁹J

Unknown:

Wavelength of the photon   = ?

Solution:

The energy of a photon can be expressed as;

     E = \frac{hc}{wavelength}

    hc  = E x wavelength

     Wavelength  = \frac{hc }{E}  

  h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s

  c is the speed of light  = 3 x 10⁸m/s

  E is the energy  

   Wavelength = \frac{6.63 x 10^{-34} x 3 x 10^{8} }{3.38 x 10^{-19} }    = 5.89 x 10⁻⁷m

The most important commercial ore of chromium is chromite (FeCr2O4). One of the steps in the process used to extract chromium fr
Mars2501 [29]

Answer:

1 mole FeCr2/ 1 mole FeCr2O4

Explanation:

We have to write down the equation of the reaction before we can answer the question;

2C(s) + FeCr2O4(s) -------> FeCr2(s) + 2CO2(g)

By inspection of this reaction equation, we can clearly see that the mole ratio of the reactants and products is 2:1:1:2.

Specifically, the ratio of chromites to ferrochrome is 1:1

Hence;

The mole ration required to convert chromites to ferrochrome is;

1 mole FeCr2/ 1 mole FeCr2O4

Shkiper50 [21]

A lot of theories exist in the world today regarding energy. The statement that explains how she can prove her theory is below:

  • He could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

Potential energy is known to be of position relative, and kinetic energy is motion relative.

The relationship that exist between the two is their ability to transform into one another. That is potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and vice versa

If an outside force acts upon an object with potential energy, that force is said to change the potential energy into kinetic energy.

The full question is below

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.

Which explains how she can prove her theory?

A

She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.

B

She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.

C

She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.

D

She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.:
