Which statement best describes a primary occurrence in an uncontrolled fission reaction.

Incomplete question. Options;

A) Mass is created and energy is released.

B) Mass is created and energy is stored.

C) Mass is converted to energy, which is released.

D) Mass is converted to energy, which is stored.

Mass is converted to energy, which is released

Explanation:

Basically, when uncontrolled nuclear fission (splitting) occurs, a radioactive atom (a mass) is split into two smaller nuclei leading to a continuous chain of fission reactions.

In other words, as the fission of the mass of the atom continues to occur, the mass is converted to energy, which is then released and more reactions occur.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
