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.

Two compounds are standing at the same temperature. Compound "A" is evaporating more slowly than compound "B." According to the
frosja888 [35]

Answer:

Option D) Compound B may have a lower molecular weight.

Explanation:

Compound A and B are standing at the same temperature yet compound A is evaporating more slowly than compound B.

This simply indicates that compound B have a lower molecular weight than compound A.

This can further be seen when gasoline and kerosene are placed under same temperature. The gasoline will evaporate faster than kerosene because the molecular weight of the gasoline is low when compared to that of the kerosene.

Darina [25.2K]

Answer:

6g O2

Explanation:

Mole to mole ratio:

A balanced chemical equation shows a chemical reaction while maintaining the law of conservation of mass. The coefficients of the substances are known to be very helpful in computations as they represent the equivalent amounts of moles of the species that would be participating in the reaction.

We set up the chemical equation and then find the balanced chemical expression.

S+O2→SO3

Balance 

2S+3O2→2SO3

We use the following values for the variables:

mS=4.0 gm

We proceed with the solution.

mO2= 4 g S × 1 mol S/ 32 g S × 3 mol O2/ 2 mol S × 32g O/ 1 mol O2

mO2 = 6 g
