Hello!
Find the Energy of the Photon by Planck's Equation, given:
E (photon energy) =? (in Joule)
h (Planck's constant) = 
f (radiation frequency) = 
Therefore, we have:
I Hope this helps, greetings ... DexteR! =)
Cu⇒ 1 atom
N⇒2 atoms
O⇒6 atoms
Total 9 atoms
<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
<em>(empirical formula) n = molecular formula </em>
Chemical formula : Cu(NO₃)₂
Number of Cu : 1
Number of N : 2
Number of O = 2 x 3 = 6
Total atoms in Cu(NO₃)₂ : 1 + 2 + 6 = 9

I just got it right in the test :)
Answer:
<u>Nucleus</u> - The central part of the atom containing protons and neutrons.
<u>Electron</u> - A positively charged particle located in the nucleus of an atom.
<u>Proton</u> - A positively charged particle located in the nucleus of an atom.
<u>Electron Cloud</u> - The area of the at surrounding the nucleus where electrons can be found.
<u>Neutron</u> - a negatively charged particle that orbits the nucleus of an atom.
