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.
Answer:
Because the number of subatomic particles is finite.
Explanation:
You probably know that in addition to electrons, protons, there are many other subatomic particles with strange names like quarks, neutrinos, muons, bosons, etc.
There are many ways in which these could theoretically be combined to make atoms of new elements.
However, the number of different subatomic particles is finite, so the number of possible combinations is also finite.
Even if scientists discover more new subatomic particles, the number of possible combinations will increase, but it will still be finite.
Thus, there is a finite number of elements in the universe.
The mass of this 82.5 pounds
Answer:
Mixtures are not chemically united, so they can be divided using physical methods.
Sand is a mixture. (Because different rocks have different chemical compositions.)
