Answer:

<em><u>It is also used for getting a quick, explosive start, when the player is beginning to swim. Greater elevation of the Polo player is created by a stronger eggbeater kick which results in a better rotation and stronger pass or shot. Overuse of the eggbeater kick has been a cause of knee injuries in water polo players.</u></em>

How should the ph of a 0.1 m solution of nac2h3o2 compare with that of a 0.1 m solution of kc2h3o2?
Semenov [28]

We have that for the Question it can be said that the NaOH combines with CH_3COOH to produce CH_3COONa (Salt)

From the question we are told

how should the ph of a 0.1 m solution of <em>nac2h3o2</em> compare with that of a 0.1 m <u>solution </u>of kc2h3o2?

Generally

with  the ph of a 0.1 m solution of <em>nac2h3o2</em> compared with that of a 0.1 m <u>solution </u>of kc2h3o2 ,we see that the salt produce  is a weak acid and strong akali salt

We see that the salt produced in water gives a base from the derived weak acid

The salt produce is CH_3COONa

Therefore

the NaOH combines with CH_3COOH to produce CH_3COONa (Salt)

Mixing Strong Acids with Strong Bases What is the pH of the solution that results from mixing 8.00 mL of 0.030 M perchloric acid
garik1379 [7]

Answer: PH= 1.4

Explanation:

n(mole)= concentration(c)× volume(v)

n(HClO4) = 0.08 ×0.03

n(HClO4)= 0.0024 mole

n(Ba(OH)2) = 0.28 × 0.05

n(Ba(OH)2) = 0.014

2HClO4 + Ba(OH)2.....>Ba(ClO4)2 + 2H2O.

Hence, the limiting reagent is perchloric acid. According to the reaction:

0.0024 HClO4 req 1/2× 0.0024 of Ba(OH)2.

n(Ba(OH) reacted= 0.0012

Excess n(Ba(OH)2) = 0.014-0.0012

Excess n(Ba(OH)2) = 0.0128

Conc(Ba(OH)2) unreacted = 0.0128/.32 (vol. of mix is 32ml)

= 0.04M = [H+]

PH = -log[0.04] = 1.397

PH= 1.4
