Na fission reaction of u-235, there was a release of 9.20 × 1011 kj of energy. what amount of mass in kilograms would have been lost? recall that c = 3 × 108 m/s.

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
