this is a very hard question
The one that does not demonstrates the law of conservation of matter would be the third option:
<h3>What is law of conservation of matter? </h3>
It is a law that explains that matters are conserved during the course of chemical reactions. They can neither be destroyed nor created.
Thus, the number of moles of the species in a reaction remains the same before and after the reaction.
Thus, an equation that demonstrates the law of conservation of matter will be balanced in terms of the number of moles of species.
The only equation, in this case, is
There are 3 oxygen species on the reactant while 5 are present on the product side.

Answer:
hydrogen atom when it drops from N 5 to N 2?
so, 275 kJ of energy is released when one mole of electrons "falls" from n = 5 to n = 2. E = hc/λ (this energy corresponds to the energy of one photon; the energy calculated in this problem is for one mole of photons so we will change this after we change the units from kJ to J)
