First, we must understand what diffusion is! Diffusion is the movement of particles from a high concentration to a lower concentration, in order to reach equilibrium. Cells in particular need this to maintain homeostasis, or an internal equilibrium (stability).
Do you mean molecular size or composition, perhaps? Bigger particles are harder to move than smaller molecules. Additionally, physical constitution of a particle will affect the rate of diffusion. Think of a mouse squeezing under a door as compared to a rock, of the same size. A mouse will more easily be able to squeeze through the gap
Answer:
1. Solute potential= -2.43 bars
2. Solution to root tissue
Explanation:
The solute potential is the potential or concentration gradient exerted by the solute in a solution.
The mathematical expression of the solute potential is
= -iRCT, where i= ionization of molecule
C- concentration of a molecule
R - pressure constant (0.0831)
T- Temperature (kelvin)
According to the given question,
i=1 ( sucrose is non-polar)
R= 0.0831
T= 273+ 20= 293
C= 0.1
Putting the values in -iRCT
we will have solute potential = -2.43 bars (high water potential)
Since the potential in root tissue is -3.3 bars. (low water potential)
We know that water moves from high water potential to low water potential and the water will move from the solution to the root tissue that is from -2.43 bars to -3.3 bars
Exchange rate is 2 guilders for every 3 florins
The conversion factor will be
2 guilders / 3 florins = 3 florins / 2 guilders = 1
so if we wish to convert 17 guilders to florins we will use following conversion factor
3 florins / 2 guilders = B / C
D = 17guilders X 3 florins / 2 guilders = 25.5 florins
Answer:
2
Explanation:
1 is definitely wrong
density must be lower to atop another liquid
in 3 ,I consider the example of water and oil whi has a lower boiling point
Answer is: there are two compounds with molecular formula C₂H₆O, one alcohol and one ethar.
Alcohol with molecular formula C₂H₆O is ethanol or ethyl alcohol (C₂H₅OH).
Ethanol is a volatile, flammable, colorless liquid with characteristic odor.
Ether with molecular formula C₂H₆O is dimethyl ether (CH₃OCH₃).
Dimethyl ether is a colorless gas.
