What is the energy per mole of photons, in kJ/mol, emitted by an argon ion laser which produces a green beam with a frequency of
Serga [27]

Answer:

Energy per mole of photons = 2.31 × 10^2 KJ/mol

Explanation:

Energy, E = hf;

Where h is Planck's constant = 6.63 ×10^-34, and f is frequency of the photons.

E = 6.63 × 10^-34 × 5.8 × 10^14

E = 3.84 × 10^-22 KiloJoules

I mole of photons contains Avogadro's number of particles, 6.02 × 10^23

Therefore, the energy per mile of photon is 3.84 × 10^-22 KJ × 6.02 × 10^23

Energy per mile of photon = 2.31 × 10^2 KJ/mol

Draw a Lewis structure for HCCl3 . Include all hydrogen atoms and show all unshared pairs and the formal charges, if any. Assume
andrey2020 [161]

Answer:

See answer below

Explanation:

First, let's explain what a Lewis structure is.

A lewis structure in short words is a draw of an atom or molecule showing how the electrons bond with another electrons of atoms, and also shows the unshared pair of electrons, which are the electrons that do not bond in the molecule. In the case of an atom, it shows all the available electrons it has to be shared and bonded with another atom to form a molecule.

With this said, in order to draw the lewis structure we need to know how many electrons the atoms involved have. To know this, we need to write the electronic configuration of the atoms, based on it's atomic number.

In the case of Hydrogen (Z = 1), Carbon (Z = 6) and Cl (Z = 17):

[H] = 1s¹     1 electron available.

[C] = 1s² 2s² 2p²   In this case, we have 4 electrons.

[Cl] = 1s² 2s² 2p⁶ 3s² 3p⁵  In this case, 7 electrons.

Now that we have the configuration, and the available electrons, we need to draw the atoms. The Carbon is the more electronegative atom of them, so, the bonding will be formed based on this atom as the central. So the other atoms will just bond and shared a pair of electron with the carbon. The HCCl₃ can be treated as CH₄, with a tetrahedrical form.

The picture below shows the lewis structure.

Hope this helps

What is the force exerted if a 52kg student accelerates into their desk at 5/ms2
murzikaleks [220]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{260 \: newton}}}}}

Explanation:

Mass ( m ) = 52 kg

Acceleration ( a ) = 5 m / s²

Force ( F ) = ?

According to Newton's second law of motion ,

\boxed{ \sf{force = mass \times acceleration}}

\longrightarrow{ \sf{force = 52  \times 5}}

\longrightarrow{ \sf{force = 260 \: newton}}

Hope I helped!

Best regards! :D

<h3>Answer:</h3>

D. Allotrope

<h3>Explanation:</h3>

What is allotropy?

  • Allotropy refers to the existence of an element in more than one physical forms.
  • Allotropes are therefore different forms of an element with different physical properties or chemical arrangements.

What are some examples of allotropes?

  • Examples of elements that exhibit allotropy include, sulfur and carbon.
  • Allotropes of carbon are diamond and graphite.
  • Allotropes of sulfur are monoclinic sulfur and rhombic sulfur.
