The sun of the protons a D neutrons in the nucleus of an atom is called the ATOMIC MASS
B
1 mile=4 poles
if 5 poles pass by than she´s going around 1.25 miles per min
rounded up = 1.3 mil/min
Answer:
20 atm / (R . 321 K . i) = M
Explanation:
Osmotic pressure is a colligative property which is determined by the solute.
Solutes over solutions, can increase the osmotic pressure which is calculated like this:
P = M . R . T
where P is pressure, M is molarity, R the Universal Constant Gases and T, the absolute Temperature. We also have to consider the Van't Hoff factor, i, numbers of ions dissolved. Ionic salts determine more osmotic pressure than organic compounds, where i = 1. Then, the complete formula is:
π = M . R . T . i
To determine molarity, osmotic pressure divide all the terms:
20 atm / (R . 321 K . i) = M
R = 0.082 L.atm/mol.K
If you see all the units in R, they will be cancelled, so finally the answer will be mol/L, which is molarity. The i term has no unit!.
Answer:
You would use an electrolytic cell.
Answer: A
Explanation: Beach deposits and wind blown deposits generally show good sorting because the energy of the transporting medium is usually constant.
