Answer:
The protonated form is predominant when aspirin is absorbed more readily. The ratio of conjugate base to acid is 1 to 100.
Explanation:
Aspirin is more readily absorbed when it is protonated, that is when pH is lower than pKa (<em>more H⁺ available in the medium</em>). We can confirm this using Henderson-Hasselbalch equation for pH = 1.5:

When aspirin is absorbed more readily the ratio of conjugate base to acid is 1 to 100, being the acid the <em>predominant</em> form.
Answer:
2Al + 3Ni(SO4) -------> 1Al2(SO4)3 + 2Ni
Explanation:
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
