What is the ph of a buffer consisting of 0.200 m hc2h3o2 and 0.200 m kc2h3o2? the k a for hc2h3o2 is 1.8×10−5. view available hi
AURORKA [14]
PH = pKa + log \frac{[base]}{[Acid]}
Acid  is HC₂H₃O₂ and conjugate base is KC₂H₃O₂,
pKa = - log Ka = - log (1.8 x 10⁻⁵) = 4.74
so pH = 4.74 + log (0.2/0.2) = 4.74
This is called maximum buffer capacity (when acid conc. and base conc. are equal) the pH = pKa in this case

a car traveling at 20 m/s starts to decelerate steadily it comes to a complete stop in 10s .what is its acceleration
Anna007 [38]

A car traveling at 20 m/s starts to decelerate steadily it comes to a complete stop in 10s. The equation for the acceleration is velocity divided by time. So divide 20 m/s by 10 s and you will get an acceleration of 2 m/s2.

What is the volume of an object that has a mass of 5.80 g and a density of 6.35 g/mL?
umka2103 [35]

Answer:

1.09 mL

Explanation:

Density is a measure of a substance's mass over its volume.

d = m/v

We can rearrange the equation to solve for volume, using algebra.

v = d/m

Therefore v = 6.35/5.80 = 1.09 mL

Neon doesn't take part in chemical reaction why give reason​
ankoles [38]
Neon has filled its outer shells, therefore it is very stable and does not need to react with other elements and doesn’t form compounds.
