Answer:
crystal size I think hope this helps
V1 = 30 mL
P1 = 760 torr
P2 = 1520 torr
V2 = ?
applying Boyle's Law
P1*V1 = P2*V2
760 torr * 30 mL = 1520 torr * V2
V2 = 760 torr * 30 mL / 1520 torr
( C ) is correct
1. Oxidation
2. Rapid Combustion
3. Respiration
4. Souring
5. Calcium
6. Photosynthesis
I hope this helps you out :D
C distillation you would evaporate the water into another container leaving you with the salt free water
