Read the scenario. Ammonia is obtained from a reaction between nitrogen and hydrogen gases. The mole ratio between hydrogen gas and nitrogen gas is 3 to 1, and the mole ratio between ammonia and hydrogen gases is 2 to 3.

Transmutation is the process of transforming one element into another through nuclear reactions. What will be the nuclide produced when Cf-249 is bombarded with C-12? Four neutrons are also produced by the reaction.
