When 100.0 mL of 0.40 M of HF and 100.0 mL of 0.40 M of NaOH are mixed, the resulting mixture is:a. a strong acid b. a strong base c. a weak acid d. a weak base e. a buffer

d. A weak base

Explanation:

For this question, we have to start with the reaction between and . So:

Now, we have to analyze each compound:

Fluorhydric acid HF this is a strong acid because it has the ability to produce hydronium ions

Sodium hydroxide NaOH this is a strong base because it has the ability to produce hydroxide ions

Sodium fluoride NaF is a salt in which the cation is and the anion is

Water Is a neutral molecule usually the solvent

Now, we have the reaction of a strong acid with a strong base. If we remember the conjugated base theory, a strong acid will produce a weak base. So, NaF is a weak base. We also have water, but this is a neutral molecule. With this in mind, the answer is d.

I hope it helps!

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
