Answer:
33 %
Explanation:
Step 1: Given data
Initial moles of the acid (nHA(0)): 6 mol
Moles of the conjugate base at equilibrium (nA⁻(eq))
Step 2: Write the balanced generic acid dissociation reaction
HA(aq) ⇄ A⁻(aq) + H⁺(aq)
Step 3: Calculate the percent ionization
We will use the following expression.
Answer:
irreversible changes
Explanation:
Most chemical changes are permanent and cannot be reversed. That is because a chemical change involves changing the molecular composition which can't be reversed. A common example of a chemical change would be burning wood. The wood burning into ash is changing the molecular composition of the wood transforming it to ash. Now can ash be changed back into wood? No, it is a "irreversible change."
Hope this helps.
Answer:
A "chaser," a high-boiling compound whose vapors will displace the vapors of the desired low-boiling compound, can be used to distill a small amount of compound.
A smaller fractionation apparatus or a Vigreux column could be used instead.
