The chemical formula does not show how the atoms are connected to one another
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
Substances have different tendencies to donate or accept electrons. When a really good donor meets a great acceptor, the chemical reaction releases a lot of energy. Oxygen (O2) is the best electron acceptor and is used in many aerobic reactions (reactions with oxygen). Hydrogen gas (H2) is a good electron donor.
When O2 and H2 are combined, along with a catalyst, water (H2O) is formed. This example of a redox reaction can be written like this:
