Answer:
Explanation:
Hello,
In this case, we have a second order kinetics given the second power of the concentration of chlorine (V) oxide in the rate expression, thus, the integrated equation for the concentration decay is:
Thus, the final concentration for a 94% decrease is:
Therefore, we compute the time for such decrease:

No, when ascending, you would weigh more, and when you descend, you weigh less.
This is due to the difference in the effect of gravity.

Light waves are the fastest in existince.
Answer: The vapor pressure of the solution at is 460.63 mmHg
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= relative lowering in vapor pressure
i = Van'T Hoff factor = 1 (for non electrolytes)
= mole fraction of solute =
Given : 11.79 g of chlorophyll is present in 153.2 g of diethyl ether
moles of solute (chlorophyll) =
moles of solvent (diethyl ether) =
Total moles = moles of solute + moles of solvent =0.01319 + 2.067 = 2.080
= mole fraction of solute =
Thus the vapor pressure of the solution at is 460.63 mmHg
