If the wavelength of light will cause electrons to be removed from the metal (creating the photoelectric effect). What is the ef

fect of doubling the photon flux of light?
Chemistry

Answer:

The number of photoelectrons are increased

Explanation:

According to Albert Einstein, when light falls on a clean metal surface, electrons are ejected from the clean metal surface. This is known as photo electric effect.

The kinetic energy of the emitted photoelectron depends on the energy of the incident photon and the work function of the metal. If the energy of the incident photon is less than the work function of the metal, photoelectric effect does not occur.

Below a given threshold frequency or wavelength called the threshold frequency or threshold wavelength photoelectric effect does not occur.

However, doubling the photon flux of light doubles the intensity of the light. This only leads to increase in the number of photons and have nothing to do with the energy of the emitted photoelectrons.

Convert 7.50 mol of Li₂O to grams
Natali5045456 [20]

Answer:

223.5 g

Explanation:

The formula between the number of moles, mass and Mr can be used to convert moles to grams.

<em>Number of moles = mass ÷ Mr</em>

So, mass = number of moles × Mr

  Mr of Li₂O = (6.9 × 2) + 16 = 29.8

∴ Mass = 7.5 × 29.8 = <u>223.5 g</u>

For the simple decomposition reaction AB(g) → A(g) + B(g) rate = k[AB]2 and k = 0.20 L/mol·s. If the initial concentration of AB
Pepsi [2]

Answer:

[AB] = 0.66M

Explanation:

rate = change in concentration/time

Initial concentration of AB = 1.5M

Let the concentration of AB after 10.3s be y

Therefore, rate = 1.5 - y/10.3

The rate equation is given as

rate = k[AB]^2 = 0.2y^2

0.2y^2 = 1.5 - y/10.3

2.06y^2 = 1.5 - y

2.06y^2 + y - 1.5 = 0

Using the quadratic formula

y = [-1 + or - √(1^2 -4×2.06×-1.5)/2(2.06)]

The value of y must be positive

y = (-1 + √13.36)/4.06 = -1+3.66/4.06 = 2.66/4.06 = 0.66

Concentration of AB after 10.3s is 0.66M

Why are(±)-glucose and (-)-glucose both classified as D sugar​
vazorg [7]

Answer:

See explanation

Explanation:

We must remember that the D / L nomenclature refers to the orientation of the hydroxyl group on carbon 5. If the "OH" is on the right we will have a D configuration. Yes, the "OH" is on the left we will have an L configuration. (See figure 1)

Now, the orientation of this "OH" has nothing to do with the ability of the molecule to deflect polarized light. If the molecule deflects light to the left we will have the symbol "(-)" (levorotation) if the molecule deflects light to the right we will have the symbol "(+)" (dextrorotation).

So in the "D" configuration, we can have both a right (+) and a left (-) deviation.

I hope it helps!
