Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The o

smotic pressures required for this process can be as high as 20.1 atm. What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 24 C?

Answer:

0.825 M

Explanation:

The osmotic pressure is a colligative property, that can be calculated using the following expression.

π = M × R × T

where,

π is the osmotic pressure

M is the molarity

R is the ideal gas constant

T is the absolute temperature (24°C + 273 = 297 K)

M = π / R × T = 20.1 atm / (0.08206 atm.L/mol.K) × 297 K = 0.825 M

Single and double replacement reactions practice WS CuCl2 +<br> F2 »<br> CuF2<br> +<br> Cl2
Lapatulllka [165]
CuCl2+F2—>CuF2+Cl2.
This is a single replacement because there is one compound and one element. Picture Cu as ‘A’ Cl2 as ‘B’ and F2 as ‘C.’ So AB+C—>AC+B. A and B “broke up” and that resulted to A going with C to create the compound CuF2 leaving Cl2 alone.

1. Energy is expended when a force moves matter across a distance. True/False
Novosadov [1.4K]
1. True
2. True
3. False
4. True
5. True

3. Heat can be thought of as the movement of particles (molecules etc). The faster they move the hotter things are. Energy of movement is called kinetic energy. Temperature is a measure of the average kinetic energy of the particles, while thermal energy is the total kinetic energy of the particles.
