A buffer solution contains 0.303 M C6H5NH3Cl and 0.424 M C6H5NH2 (aniline). Determine the pH change when 0.108 mol HClO4 is added to 1.00 L of the buffer. pH after addition − pH before addition = pH change =

Chewy,wrapped,not in all white,the wrapper is clear

No. an alpha particle is a pair of protons and a pair of neutrons, i.e. a helium

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
