I think it’s law conservation of mass.
So 200g(NH3)-47g(N2)=153g(H2)
H2+N2—->NH3
Hello there!
The correct answer is B. Electrons will be added to an atom starting from the lowest possible level or sublevel.
Hope This Helps You!
Good Luck :)
<u>Answer:</u> The correct answer is option A.
<u>Explanation:</u>
Nuclear fission reactions are a type of nuclear reactions in which larger nuclei breaks apart into two or more smaller fragment releasing alpha, gamma of beta particles.
There are 3 types of particles that can be released during this process:
1. Alpha particles: These particles are released when a nuclei undergoes alpha-decay process.

2. Beta particles: These particles are released when a nuclei undergoes beta-minus decay process.

3. Gamma radiations: these radiations are released when an unstable nuclei gives off excess energy by a process of spontaneous electromagnetic process.

Hence, any of these particles can be released during the process of fission reaction with smaller atoms.
Therefore, the correct answer is option A.
The two ways that energy can be transferred are by doing work and by heat transfer.
