One of the fission products that causes major concern is Sr-90, since it is incorporated into milk and other high-calcium foods. Sr-90 undergoes beta decay with a half-life of 28.1 years. What percentage of the Sr-90 that was formed in the detonation of the first fission bombs in August 1945 is still present in the environment in August 2094?
using this equation N2(g)+3H2(g)-->2NH3(g) if 10500 L H2 gas is reacted with an excess of N2 gas at 200 atm and 500 degrees how many moles of ammonia gas would be produced, assuming a 15% yield
