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:
The diagram is attached.
Explanation:
Peptide just refers to two or more amino acids liking together. A dipeptide consists of two amino acids linking together. A polypeptide is more that two amino acids linking together.
Answer: The pH 0f 0.10 solution of HCl is 1.00
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
According to stoichiometry,
1 mole of 
gives 1 mole of 
Thus 
moles of gives =
moles of
Putting in the values:
![pH=-\log[0.10]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B0.10%5D)
Thus pH 0f 0.10 solution of HCl is 1.00
The balanced chemical reaction is:
<span>Ca + Cl2 = CaCl2
</span>
We are given the amount of calcium metal to be used for this reaction. This will be the starting point for the calculations.
56 g Ca ( 1 mol Ca / 40.08 g Ca) (1 mol Cl2 / 1 mol Ca) ( 22.414 L Cl2 / 1 mol Cl2 ) = 31.32 L Cl2 gas produced from the reaction
<em>Answer:</em>
<em>Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.</em>
