Answer:
C. polarity
Explanation:
Water is polar that is why it is a universal solvent.
<span>570 torr.
The ideal gas law is
PV = nRT
where
P = pressure
V = volume
n = number of moles of gas particles
R = Ideal gas constant
T = absolute temperature
Since the value n, R, and T remain constant for this problem, that indicates that if the volume is doubled, the pressure will be halved. So the new pressure will be 1.50 atm / 2 = 0.750 atm. Now we just need to convert that from atm to torr. 1 atm is equal to 760 torr, so 0.750 atm * 760 torr/atm = 570 torr.</span>
Answer:
During the recharge process, the water infiltrates at the land's surface and flows through the unsaturated zone. It then crosses the water table and enters the groundwater system. Chloride (NaCl) is important and necessary because the sodium ions are held loosely and exchanged easily with calcium and magnesium ions.
