100 x
(Above is proportions I used to get the answer)
x = 0.73% which is the answer.
Answer:
D) 5.15
Explanation:
Step 1: Write the equation for the dissociation of HCN
HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)
Step 2: Calculate [H⁺] at equilibrium
The percent of ionization (α%) is equal to the concentration of one ion at the equilibrium divided by the initial concentration of the acid times 100%.
α% = [H⁺]eq / [HCN]₀ × 100%
[H⁺]eq = α%/100% × [HCN]₀
[H⁺]eq = 0.0070%/100% × 0.10 M
[H⁺]eq = 7.0 × 10⁻⁶ M
Step 3: Calculate the pH
pH = -log [H⁺] = -log 7.0 × 10⁻⁶ = 5.15
Possible products in this reaction are the products 2 and 3.
<h3>What is the Friedel Crafts reaction?</h3>
The Friedel Crafts reaction is one in which the electrophile is created by a Lewis acid reaction between the AlCl3 and the alkylhalide reactant .
Now we know that there is the possibility of two products in this reaction due to a resonance shift as such possible products in this reaction are the products 2 and 3.

Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
