The half-life of

is 3.26 days. This isotope decays by beta emission to a highly unstable intermediate that decays rapidly to a stable product by beta emission.
a. What is the ultimate product obtained from Te-132? Write a balanced equation for this reaction.
b. Gaseous H2Te is made with Te-132. When the tellurium isotope decays, the H2Te produces H2 and the ultimate decay product of Te-132. Write a balanced equation for the formation of stable products from H2 132Te.
c. If a pure sample of 0.0125 mol of H2Te made entirely of Te-132 is placed in an evacuated 1.50-L flask, how much H2Te remains after 99.0 h? If the temperature is 25°C, what is the pressure in the flask?
