8 0

Answer:

18.066×10^23 molecules of O2.

Explanation:

There are 6.022 × 10^23 molecules in 1 mole of any compound, irrespective of elements or the mass of compound. Thus in 3 moles of O2, there are 3 ×6.022× 10^23 molecules of O2 or 18.066×10^23 molecules of O2.

6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume
alex41 [277]

Answer:

1.71atm

Explanation:

The following were obtained from the question:

V1 (initial volume) = 6L

P1 (initial pressure) = 1atm

V2 (final volume) = 3.5L

P2 (final pressure) =?

Using the Boyle's law equation:

P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

1 x 6 = P2 x 3.5

Divide both side by 3.5

P2 = 6/3.5

P2 = 1.71atm

The final i.e the new pressure inside the piston is 1.71atm

A 10% glucose solution is placed in a dialysis tubing bag. the dialysis tubing bag is placed in a beaker that contains a 5% gluc
alexandr1967 [171]
The highest concentration of water would be found in the 5% solution. The concentration given above is percent of glucose, so the solution contain 5% of glucose and 95% of water. Comparing it to 10% of glucose solution which will have 10% glucose and 90% water, clearly, it is the 5% solution that has the highest amount of water in the solution. <span>Percentage by a certain unit is the amount of that unit of a component in a mixture per 100 units of the total mixture. </span>

Why do substances with weak intermolecular forces form solids at low melting points?
Advocard [28]
To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.
