In lab, a dialysis bag was filled with a 10% sucrose solution and placed in an unlabeled beaker filled with clear liquid. The di

alysis bag was made of a semipermeable membrane that allowed the free passage of water, but was not permeable to sucrose. After two hours, the bag in the beaker decreased in size, lost volume, and became flaccid. Therefore, at the beginning of the experiment, the solution in the bag was ____________ compared to the solution in the beaker. g

Answer:

Of lower concentration or less concentrated

Explanation:

Osmosis is the movement of solvent from a region of lower concentration of solute to a region of higher concentration of solute through a semipermeable membrane in order to equalize the concentration of the solutions on both sides.

Since the membrane of the bag is semipermeable, then the fact that the bag in the beaker decreased in size, lost volume, and became flaccid indicates that the solution in the bag is of lower solute concentration than the solution in the beaker hence the movement of water molecules into the beaker by osmosis.

ethane, c2h6, has a boiling point of -89°c at standard pressure. ethanol, c2hsoh, has a much higher boiling point than ethane at
Kipish [7]
Ethanol is a polar molecule containing hydrogen bonds at the OH groups. These bonds are much stronger and therefore take much more energy to break, hence the higher melting and boiling points

Ethane on the other hand is non-polar as it is a hydrocarbon and only contains London Dispersion forces between molecules, which are the weakest of the intermolecular forces, meaning it is easy to break them.

4. Does an atom of an element always have the same number of neutrons as other atoms of the same
Sergeeva-Olga [200]

Explanation:

No. Isotopes are atoms of the same element with different atomic masses (due to the different number of neutrons)

For example, carbon exists as carbon-12 and carbon-14, which both have 6 protons but have 6 and 8 neutrons respectively.
