Answer:
The celery cells are hypertonic to freshwater but hypotonic to 0.2M solution of NaCl
Explanation:
<em>A hypertonic solution is one that whose concentration is more than that of the sap of the cell placed in it while a hypotonic solution has lesser concentration compared to the cell sap.</em>
When the surrounding solution of a cell has more concentration than the cell sap, water molecules moves from the cell to the surrounding solution until equal concentration is established between the outer and the inner solution. The cell lose water and become flaccid. Such cell is said to be hypotonic to the surrounding solution.
On the other hand, when the surrounding solution has lower concentration than the cell sap, water moves from the surrounding solution into the cell and as a result, such cell becomes turgid. The cell is said to be hypertonic to the surrounding solution.
Water moves from the cell sap to the surrounding 0.2M NaCl solution, meaning that celery cells are hypotonic to 0.2M NaCl. On the other hand, water moves from surrounding freshwater into the cell, meaning that celery cells are hypertonic to freshwater.
Answer:
Decanitrogen is molecular
Explanation:
Explanation:
The presence of residual solvent is a factor that affects the glass temperature of the polymer. This is because a residual solvent decreases the free volume in a polymer. All types of polymers have total occupied volume, which is composed of an occupied volume and a free volume. The free volume is the volume needed for the polymer chains to move around. Thus, if there is a big free volume in the polymer it will decrease the glass transition temperature and will both decrease and broaden the melting range of the crystals.
In a polymer with crystalline spherulites and the surrounding amorphous, will have a bigger surrounding amorphous with the presence of residual solvent. Which will decrease the melting range of the crystals. The structure found on the interior of the spherulites is pure crystalline polymer, so probably the residual solvent will not be inside them.
(2.5)(3.5)=10V²
The answer is 0.875 repeating liters.
Noble Gas. Metals have 1 or 2 Valence Electrons. Halogens have 7 Valence Electrons. Semi-Metals can have different amounts.
