the atomic number determines the tyoe of element an atom is.
the atomic number means the number of protons in an atom.
atoms of different elements have different numbers of protons and different atomic numbers so you can identify the element based on the atomic number
Answer:
it depends upon the material used to make the brick
The mechanism is as suggested
1) Protonation of alcohol
2) removal of water molecule to give carbocation
3) hydride shift to give more stable carbocation [rearrangement]
4) the stability of carbocation due to resonance
5) removal of proton and formation 1-phenyl-1-propanone.
This is Pinacole pinacolone rearrangement
Thus the reaction can be depicted as
If we have two gram produce 2 grams were consumed
Due to the mass conversation law which state that the mass in a isolated is neither created nor destroyed by chemical reaction or physical transformation. Therefore the mass of the product must be equal to the mass reactant
