What is the Lewis dot diagram structure for PI2F

Answers

Answer 1

Answer:

Please find attached the completed Lewis dot diagram structure for PI₂F

Explanation:

The number of valence electrons are;

Phosphorus = 5 Electrons

Iodine = 2 × 7 electrons = 14 electrons

Chlorine = 7 electrons

The total number of valence electrons = 14 + 7 + 5 = 26 electrons

2) We draw the symbol that represents the basic (general) structure of the molecule as follows;

The sheared electron pair are represented by single bond lines

3) We complete the octet structures round the fluorine and the iodine atoms as attached showing 18 electrons plus 6 shared electron pairs, with a maximum from step 2 to give a total of (18 + 6) 24 electron pairs

4) We add the 2 unaccounted valence electron on the phosphorus atom to give it the stable octet structure, which gives the completed Lewis structure

Answers

Answer:

Solute

Explanation:

A solution is made up of combination of solute and solvent.

The solute is the solid dissolved in a solvent.

Solutions are homogeneous mixtures of solutes and solvents.

In a solution the solutes are evenly distributed in the solvent. The solute is the substance dissolved to make the solution. It is usually present in smaller amount than the solvent. The solvent is the dispersing medium.

3.00 Liters of gas are stored at standard temperature and pressure. If the volume of the gas is increased to 4.00 L at a constant temperature what is the new pressure of the gas

Answers

The new pressure of the gas : 0.75 atm

Further explanation

Boyle's Law

At a constant temperature, the gas volume is inversely proportional to the pressure applied

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

P₁=1 atm ⇒ standart temperature and pressure (STP)

V₁=3 L

V₂=4 L

[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_2=\dfrac{1\times 3}{4}\\\\P_2=0.75~atm[/tex]

The velocity of seismic waves decreases suddenly when they enter the asthenosphere.

Answers

Answer: The asthenosphere is made of lighter elements.

Explanation:

The asthenosphere has obtained its name from Greek word called asthenis, which mean weak. The strength of asthenosphere is lower than that of overlying lithosphere. If the temperature of lithosphere raises high enough then asthenosphere will melt. This layer is ductile and deforms very easily.

Temperature and kinetic energy have a relationship.

Answers

Answer:

[tex]\boxed {\boxed {\sf Temperature=Average \ kinetic \ energy}}[/tex]

Explanation:

Temperature is also known as the average kinetic energy in a substance.

If there is an absence of heat in a substance, the particles move slower and the kinetic energy decreases. The temperature will be lower, because there is less kinetic energy.

If heat is present or applied, the particles move more, so kinetic energy increases. The temperature will be higher, since there is more kinetic energy.

So, the relationship is: temperature is the measure of average kinetic energy.

In the reaction below, how would adding more of reactant A affect the equilibrium of the system? (2 points)
A + B ⇄ C + D

a
Shift it to the right toward the products.

b
Shift it to the left toward the reactants.

c
Equally create more products and reactants.

d
It would have no effect.

Answers

Answer:

a . Shift it to the right toward the products.

Explanation:

In the reaction, if more of the reactant A is added to the system, the reaction will shift towards the products.

If a system at equilibrium is disturbed by changing the concentration of one of the substances, all the concentration will change until a new equilibrium point is reached. If we add more reactants, the concentration is increased and the reaction shifts to the right so as to maintain the constancy of the equilibrium constant.

Answer: a . Shift it to the right toward the products.

For visible light, explain how wavelength and energy vary for the different colors. Provide the trends in wavelength for the spectrum of light (purple to blue to green to yellow to orange to red). How is this different for energy?

Answers

Answer:

See explanation

Explanation:

If you look closely at the image attached, you will discover that the order of increasing wavelength in the visible spectrum is;

violet < indigo< blue < green < yellow < orange < red

On the order hand, the energy of the photons increases in the order;

Red < orange < yellow < green < blue < indigo < violet

Since energy follows a trend opposite to that of wavelength, we can see that the greater the wavelength of light, the lower the energy of photon corresponding to that particular colour.

Calculate the energy of the lasers in a Blu-ray player, which emit at a wavelength of 4.05x10−7 m.

Answers

Answer:

4.907 × 10^-19 J

Explanation:

The energy of the lasers in a Blu-ray player can be calculated by using;

E = hf

Where;

E = Energy of laser (J)

h = Planck's constant (6.626 × 10^-34 J/s)

f = frequency (Hz)

However, the frequency must be known first in order to calculate the energy. The frequency can be calculated using the formula:

f = v/λ

Where:

λ = wavelength (4.05x10−7 m.)

v = speed of light (3 × 10^8m/s)

f = frequency (Hz)

f = 3 × 10^8 ÷ 4.05 x 10^−7

f = 0.7407 × 10^(8 + 7)

f = 0.7407 × 10^15

f = 7.407 × 10^14 Hz

Using E = hf

E = 6.626 × 10^-34 × 7.407 × 10^14

E = 49.07 × 10^(-34 + 14)

E = 49.07 × 10^-20

E = 4.907 × 10^-19 J

Which particle remains undeflected when passing
through this electric field?
A) proton
B) electron
C) neutron
D) positron

Answers

Answer:

C) neutron

Explanation:

The particles that remains undeflected when passing through this electric field are the neutrons because they do not carry any charges on them.

Neutrons are uncharged particles. Since they do not have any charges on them, they are not affected by the electric field. Both protons and electrons are deflected by the electric field. The charges on these particles causes them to be deflected.

The particle which remains undeflected when passing through this electric field is:

C) neutron

The given diagram shows the particle traveling through a field and there are positively, negatively and neutral charged ions.

As a result of this, we can see that the neutron does not get deflected as it is passing through the electric field because they do not have any charge in them and as such cannot be drawn by the electric charge.

Therefore, the correct answer is option C
