The energy of the light with a wavelength of 415 nm is not sufficient to remove an electron from a silver atom in the gaseous phase.
<h3>Energy and wavelength of light</h3>
The energy and wavelength of light are related by the formula given below:
- Energy = hc/λ
- where, E = energy
- h = Planck's constant
- c = velocity of light
- λ = wavelength of light
<h3>Calculating the energy of the light</h3>
From the data provided:
- h = 6.63 × 10^-34 Js
- c = 3.0 × 10^8 m/s
- λ = 415 nm = 4.15 × 10^-7 m
E = (6.63 × 10^-34 × 3.0 × 10^8 m/s)/4.15 × 10^-7 m
E = 4.79 × 10^-19 J
Energy of light is 4.79 × 10^-19 J
Compared with the ionization energy of silver, the energy of the light is far less.
Therefore, the energy of the light with a wavelength of 415 nm is not sufficient to remove an electron from a silver atom in the gaseous phase.

When peroxide is swallowed, it generates oxygen bubbles in the stomach. Drinking higher concentrations of hydrogen peroxide can be very dangerous because it can cause tissue burns.
statement about enzymes that is correct is
b. they are large molecules that increase the rate of biologically important reactions
Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.
Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.
Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.
so the correct answer is B.
There would be about 1.67 x 10^25 oxygen atoms and about 3.34 x 10^25 hydrogen atoms.
