Answer:
3.025eV
Explanation:
Energy of a photon is given by
E=hν
Where h is the Planck's constant
And ν represents the frequency of the photon .
Now for violet light wavelength λ=410nm= 410x10^-9m
By using the formula ν=c/λ
where c represents speed of light I.e 3 x 10^8 m/s
Calculating energy of violet photon we have
E=hc/λ
h=6.626 x 10^-34 J.s
On inserting the value in the formula , we get
E= 4.848 x 10^-19 Joules
To convert it into electron volts we need to divide it by 1.602 x10^-19.
The final result what we have is E=3.026eV.
Note: the result calculated is according to the above value . result may vary according to the values taken .

Explanation:
is the solubility of the gas when it exerts a partial pressure of 92.4kPa.
<h3>What is Henry's law?</h3>
Mathematically, we can get this from Henry's law
From Henry law;
Concentration = Henry constant × partial pressure
Thus Henry constant = 
Henry constant = 
Hence, is the solubility of the gas when it exerts a partial pressure of 92.4kPa.

Configuration of carbon is 1s2 2s2 2p2 and the rest of all is correct
It is a nuclear reaction since a change has occurred in the nucleus. In nuclear reactions the particles in the nucleus are changed and one element is transformed into another element when particles in the nucleus gained are lost. Unlike chemical reactions which involve the electrons in an atom, nuclear reaction involve the nucleus. A nuclear reaction may be a nuclear fission or nuclear fusion; An example of nuclear reaction is where two isotopes of hydrogen (tritium and deuterium) are fused together under high pressure and temperature, to form a more stable atom of helium. This is an example of nuclear fusion reaction.
