Answer:
(3) 345 nm
Explanation:
<u>Given:</u>
Average C-C bond energy = 347 kJ/mol
<u>To determine:</u>
Wavelength of photon that can break a C-C bond
<u>Calculation:</u>
The energy (E) of a photon is related to its wavelength (λ) by the Planck's equation:
where h = Planck's constant = 6.626*10⁻³⁴ Js
c = speed of light = 3*10⁸ m/s
λ = 3.45*10⁻⁷ m
Since 1 nanometer (nm) = 10⁻⁹ m
The calculated wavelength corresponds to 345 nm
1. greenhouse gases. these are not formed because nuclear fission involves the modification of atoms. It does not give rise to other molecules.
Answer:
The first thing you will need to do is find some information about your element. Go to the Periodic Table of Elements and click on your element. If it makes things easier, you can select your element from an alphabetical listing.
Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
Explanation:
hope this helps, have a good day :-)
Answer:
it would ether be gray to black or silver to gray and black
Explanation:
because of my calculation ekasillicon would be that color because of the eyes and because of your color seeing .
