In a relationship with two variables, when one variable becomes larger by a given factor and the other becomes smaller by the same factor, the variables are said to a) inversely b) equally c) directly

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

Which of these conditions most likely produces an unstable isotope?

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.
