5. Which of the following statements illustrates osmosis?

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 process describes vaporization that takes place below the surface of a liquid? condensation melting boiling evaporation

Give one example of a pure (exact) number and of an estimated (measured) number.
