What is the [h3o+] and the ph of a benzoic acid-benzoate buffer that consists of 0.17 m c6h5cooh and 0.42 m c6h5coona? (ka of benzoic acid = 6.3 × 10^−5). be sure to report your answer to the correct number of significant figures.

and pH = 4.6

Explanation:

Construct an ICE table to calculate changes in concentration at equilibrium.

I(M): 0.17                                    0.42                0

C(M): -x                                        +x                  +x

E(M): 0.17-x                                0.42+x             x

So,

or,

or,

So,

()

So, M

Hence

they are made of gases.

they have a spherical shape.

they make energy through fusion.

the answer is c
