Answer:
Express these numbers in atomic mass units ("u"). Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. ( I asked my teacher about this too)
Explanation:
The law of conservation of energy states that energy cannot be created or destroyed but can be converted or transferred. So when you're eating a burger which has chemical energy, it is transferred to mechanical energy if you go out and ride a bicycle. Another example is when the Sun which is thermal energy shines on the apple tree, it is converted to chemical energy because the apple has chemical energy. Transferred is pretty similar.
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons.
