False, although the air is moving in an equilibrium us normal humans can not see the air actually moving. So it is false.
The best answer is, “Two clear liquids combine and turn cloudy.”
When water freezes form a liquid to a solid. That’s a physical change.
When water boils, it forms bubbles. That’s a physical change.
When you mix ethanol and water, they form a clear solution. That’s a physical change.
Answer: V2 = 35.54L
Explanation:
Applying
P1= 67.4, V1= 85, T1= 245, P2= 179.6, V2= ?,. T2=273
P1V1/ T1= P2V2/T2
Substitute and simplify
(67.4*85)/245 = (179.6*V2)/273
V2= 35.54L
Molarity of solution is defined as number of moles present in one liter solution. Mathematically, it is expressed as
Molarity =

Thus, if 1 mole of solute is present in 1 liter solution, molarity of solution is 1 M.
In present case, initial conc, of solution was 1.25 M.
∴ Number of moles of <span>co[h2o]6cl2 available initially = 1.25 mole, if the solution is 1 liter</span>
Answer:
