Which of the following pairs of compounds can you directly compare against each other theoretically? (choose all that apply) (hint - in order to compare 2 compounds theoretically, there can NOT be 2 factors that would lead to opposite conclusions)

a. Aniline vs anisole
b. Anisole vs acetanilide
c. Acetanilide vs aniline

Asolution at 25 degrees celsius is 1.0 × 10–5 m h3o+. what is the concentration of oh– in this solution?

Compare these two waves : a. the blue wave has a higher pitch, but the orange wave is louder. b. the blue and orange waves have the same volume, but the blue wave has a higher pitch. c. the blue and orange waves have the same pitch, but the blue wave is louder. d. the orange wave has a higher pitch, but the blue wave is louder.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
