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.

Which question could be best answered using the process of scientific inquiry? do different plates have different rock compositions? why did it take so long to develop the theory of plate tectonics? what are different cultural myths caused by plate tectonics? do plates move intentionally to cause volcanic eruptions?
