Which of the following mixtures, with each component present at a concentration of .1m has a ph closest to 7? -hclo and naclo-hno3 and nano3-ch3cooh and nach3coogiven: pkas 3.2e-8, large, 2e-5, 4e-4 respectively

HClO/NaClO  

Explanation:

HClO;          Kₐ = 3.2 × 10⁻⁸

HNO₃;         Kₐ = large

CH₃COOH; Kₐ = 2 × 10⁻⁵

The most effective buffer will contain an acid with a pKₐ close the desired pH.

The buffer pair HClO/NaClO is the closest match.

pH = pKₐ = -log (3.2 × 10⁻⁸) = 7.49.

HNO₃/NaNO₃ will give pH ≈ 1

CH₃COOH/CH₃COONa  will give a pH closer to 4.7

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
