Shatter into tiny pieces
The crystal may break due to the fall.
Fine particles, ground level ozone, sulfur dioxide, nitrogen dioxide, lead
1 mol of Br = 79.9 g
15.7 g / 79.9 g = 0.196 moles of atoms
I would assume so.
Given

, we can simplify the fraction to

Both would obtain the same proportions, so I don't see why putting a half cup of sugar would make things any different.
Hope this is the answer you are looking for.
