One mole of an ideal gas will occupy 22.4 liters of volume at STP.
If the only thing that changes is the pressure from 1.00 atm to 2.00 atm, then we know the initial volume, initial pressure, and final pressure. We can use Boyle's law.
Boyle's law: (initial pressure)*(initial volume) = (final pressure)*(final volume)
fill in the knowns
(1.00 atm)*(22.4 liters) = (2.00 atm)(final volume)
divide both sides by 2.00 atm
11.2 liters = final volume
The period determines the horizontal arrangement of the periodic table, I think anyways
Surface runoff, its quite obvious in the picture
Both salt and sugar have radically different properties (both ... known as table salt, is an ionic compound with the chemical formula NaCl, ...
The answer is C. Siliceous
I hope this helps!
