Anhydrous calcium chloride is hygroscopic and can attract water from the atmosphere. After anhydrous calcium chloride gets water, it will become hydrous calcium chloride. This allows the a<span>nhydrous calcium chloride to reduce water vapor continuously in the air-tight sealed container. It can be used to protect substance that can react with water or preserve food by lowering the humidity.</span>
The reaction which shows the bronsted-lowry acid reacting is HCl + H₂O → H₃O⁺ + Cl⁻.
<h3>What is Bronsted - Lowry acid?</h3>
According to the Bronsted-Lowry theory, the species which donates H⁺ ion to the solution is known as Bronsted-Lowry acid and which accepts H⁺ ion is known as Bronsted-Lowry base.
Among the given reactions, only the reaction which is showing Bronsted-Lowry acid is:
HCl + H₂O → H₃O⁺ + Cl⁻
Here HCl is a Bronsted-Lowry acid as it gives H⁺ ion in the aqueous solution.
Hence, option (3) is correct.

I believe the answer is red, they have the longest wavelength, and energy.
Hope this helps
Answer is: 0.0213M.
Reaction: N₂O₄ (g) ↔ 2NO₂ (g).
Kc = 0,211 at <span>100°C.
Kc - </span><span>equilibrium constant.
</span>c (N₂O₄) = [N₂O₄] = 0,00251M.
c (NO₂) = [NO₂] = ?
Kc = [NO₂]² / [N₂O₄]
[NO₂]² = Kc · [N₂O₄]
[NO₂] = √(Kc · [N₂O₄<span>]) </span>
[NO₂] = √(0.211 · <span>0.00215M) </span>
[NO₂] = 0.0213M.
