A scientist has a sample of uranium–238 (U–238) that is decaying to thorium–234 (Th–234). During the transmutation, a gamma ray is emitted from the nucleus. The thorium–234 daughter particle does not decay quickly enough to be detected. What kind of storage container should he store the sample in to reduce radiation exposure? Explain your answer.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
