39. suppose an aqueous solution contains both table sugar and table salt. can you separate either of these solutes from the wate
Degger [83]

Answer:

No, assuming that the salt/sugar is already dissolved

Explanation:

As long as the particle size is too big, it won't filter through. Therefore, if it is dissolved, it will pass through the filter.

If you were to throw rocks in there or something, and they are non-dissolvable, then yes.

Convert 338 L at 63.0 atm to its new volume at standard pressure.
taurus [48]

The new volume at standard pressure of 1 atm is 21294 liters.

Explanation:

Data given:

Initial volume of the gas V1 = 338 liters

initial pressure on the gas P1 = 63 atm

standard pressure as P2 = 1 atm

Final volume at standard pressure V2 =?

The data given shows that Boyle's law equation is to used:

P1V1 = P2V2

rearranging the equation to calculate V2,

V2 = \frac{P1V1}{P2}

Putting the values in the equation:

V2 = \frac{338X63}{1}

     = 21294 L

as the pressure on the gas is reduced to 1 atm the volume of the gas increased incredibly to 21294 litres.

What is the frequency of green light, which has a wavelength of 4.90 x 10
Lina20 [59]

Answer:

I found:

ν=6×10^14Hz

Explanation:

You can consider that wavelength λ and frequency ν are related through the speed of light in vacuum c as:

c = λ ⋅ ν

so:

3 * 10⁸ = 4.9 * 10-⁷ * V

v =3 *10⁸/ 4.9 *10⁻⁷ = 6 * 10¹⁴HZ
