The frequency of radiation : 1.2 x 10¹⁵ Hz
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
<h3>f = c / λ
</h3>
c = speed of light
= 3.10⁸ m/s
λ = wavelength
Wavelength-λ is 2.51 x 10⁻⁷m
The frequency :

350 nm because the magnesium reacts very aggressively toward these kind of situations.
Salts in order of growing pH of their 0.1 M aqueous solutions: NaHCO₃, , NaHSO₄ , Na2CO3, NH₄NO₃ .
<h3>How do you determine the pH of a substance?</h3>
To calculate the pH of an aqueous solution you want to recognize the attention of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
<h3>What makes a salt acidic?</h3>
Since the cation acts as weak, a salt with an anion of a strong acid and a cation of a susceptible base produces an acidic solution with a pH much less than 7.
In this case, the anion will become the spectator ion, while the weak acid dissociates in water and yields H3O+ ions.
