The energy of the photon with the wavelength of 584 nm is 3.4×10¯¹⁹ J
<h3>How to determine the frequency of the photon</h3>
- Wavelength (λ) = 584 nm = 584×10⁻⁹ m
- Speed of light (v) = 3×10⁸ m/s
- Frequency (f) = ?
f = v / λ
f = 3×10⁸ / 584×10⁻⁹
f = 5.14×10¹⁴ Hz
<h3>How to determine the energy</h3>
- Planck's constant (h) = 6.626×10¯³⁴ Js
- Frequency (f) = 5.14×10¹⁴ Hz
- Energy (E) =?
E = hf
E = 6.626×10¯³⁴ × 5.14×10¹⁴ Hz
E = 3.4×10¯¹⁹ J

Answer:
In 3K2O3 - 6 K atoms, 9 O atoms
In 2H3NCH3Br - 12 H atoms, 2 N atoms, 2 C atoms, 2 Br atoms
In 4 Ar2CO3 - 8 Ar atoms, 4 C atoms, 12 O atoms
Explanation:
All you need to do is multiply the coefficient by the number of each atom in the compound. For example, H3NCH3Br has 1 nitrogen, 1 carbon, 1 bromine, and 6 hydrogens. If you have 2H3NCH3Br, just multiply all those numbers by 2.
In the reaction, Na⁺ + 6H₂O ⇆ Na (H₂O)⁺₆, Na⁺ is a Lewis acid and H₂O is a Lewis base.
<h3>
What is a Lewis acid-base reaction?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- Here Na⁺ that is electron deficient accepts electrons from the electron donor, H₂O
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.

<span>Helium = 1
Carbon = 8
Nitrogen = 8
Strontium = 52
Tellurium = 71
If you look on a periodic table, on each element there is a number on
the top left. This represents the number of protons in an atom. Protons
have a mass of 1 (in relative to Carbon-13)
If we take nitrogen-15 for example; The number 15 tells you that the
isotope has a mass of 15. Now if you look on the periodic table,
Nitrogen has a proton number of 7. Only protons and neutrons have a
mass, electrons are considered to be negligable. Therefore the number of
neutrons Nitrogen-15 contains is 15 - 7 = 8 </span>
