6 0

Answer:

0.25 M ammonium nitrate + 0.40 M ammonia

0.39 M hypochlorous acid + 0.25 M potassium hypochlorite

0.12 M hydrofluoric acid + 0.14 M sodium fluoride

Explanation:

A buffer consists of a weak acid and its salt or a weak base and its salt.

NH₃ is a weak base, and HClO and HF are weak acids.

B is wrong. HNO₃ is a strong acid.

C is wrong. KOH is a strong base.

An aqueous solution contains 0.29 M of benzoic acid (HA) and 0.16 M of sodium benzoate (A-). If the pH of this solution was meas

Inga [223]

Answer:

pKa = 4.89.

Explanation:

We can solve this problem by using the Henderson-Hasselbach equation, which states:

pH = pKa + log $\frac{[A^-]}{[HA]}$

In this case [A⁻] is the concentration of sodium benzoate and [HA] is the concentration of benzoic acid.

We input the given data:

4.63 = pKa + log $\frac{0.16}{0.29}$

And solve for pKa:

pKa = 4.89

Platinum is one of the most dense elements (d = 21.5 g/cm3). What is the volume of a 10.0 g sample of the metal?

kvasek [131]

Answer:

0.465

Explanation:

To find the volume of a substance, divide the mass by the density.

M/D = V

10.0 / 21.5 = 0.4651163

Then round to 3 significant figures: and the density is 0.465
