Phosphorus-32 is used in the form of Na2HPO4 in the treatment of chronic myeloid leukemia, among other things.
(a) The isotope decays by ? particle emission. Write a balanced equation for this process.
(b) The half-life of 32P is 14.3 days. If you begin with 4.9 ?g (micrograms) of radioactive 32P in the form of Na2HPO4, what mass remains after 28.6 days (about one month)?
You have prepared a saturated solution of at 20 degree celcius using 31.0 of water. How much more solute can be dissolved if the temperature is increased to 30 degree celcius.
A beaker with 115 of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 . A student adds 9.00 of a 0.430 solution to the beaker. How much will the pH change? The ..
