Explain the significance of this quote, “Heisenberg may have slept here.”
ch4aika [34]

Umm...Well...

Heisenberg's Uncertainty Principle says that we can never know both the position and rate of change of a particle at any time. We can only know one or the other. This leads to rather silly jokes that deal with uncertainty, probability, and superposition. So, saying that "Heisenberg may have slept here" is essentially saying that it is uncertain if Heisenberg slept there or not, making for a rather silly, but slightly unfunny physics joke.

Question 18 (Essay Worth 8 points)
DENIUS [597]

Yes, the law of conservation of mass holds.

Explanation:

In every chemical reaction, mass is always conserved. This implies that in chemical reaction, the process proceeds maintaining the same set of atom in the same proportion without new ones forming.

  • From the description given, decomposition of the Silver carbonate will produce a silver residue with the given mass.
  • The other mass that seems lost can be examined to be given off as carbon dioxide gas which is the other product of the reaction and oxygen.
  • Therefore, since the products are silver, carbon dioxide and oxygen, the remaining mass is that of the carbon dioxide and oxygen. It is not lost.
