34. ••• Nitrogen-13, with a half-life of 10.0 min, decays by beta emission.

(a) Write down the decay equation to determine the daughter product and whether the beta particle is a positron or electron.

(b) If a sample of pure 13N has a mass of 1.50 g at a certain time, what is the activity min later?

(c) What percentage of the sample is 13N at this time?

(d) What alternative process could have happened to the nitrogen-13? Write its decay equation and determine the daughter product for this process.
