Answer: Option (a) is the correct answer.
Explanation:
A strong acid is an acid which completely dissociates into its ions in a solution.
For example, HCl is a strong acid and it dissociates as follows.
Whereas a weak acid dissociates slightly into a solution.
Thus, we can conclude that it is true of a strong acid that it ionizes close to 100 percent in water.
Answer:
The answer is
<h2>25 mL</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of CCl4 = 40g
Density = 1.6 g/mL
The volume is
We have the final answer as
<h3>25 mL</h3>Hope this helps you
Answer:
Explanation:
Hello,
In this case, considering the dissociation of valeric acid as:
Its corresponding law of mass action is:
Now, by means of the change due to dissociation, it becomes:
Solving for we obtain:
Thus, since the concentration of hydronium equals , the answer is:
Best regards.
