Answer:
Osmotic pressure is a measure of a solution's tendency to attract or take in water from another solution when the two solutions are separated by a semipermeable membrane
The order of increasing osmotic pressure is
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
Explanation:
Osmotic pressure is the strength of movement of the solvent of a solution through a semipermeable membrane separating solutions of different concentration thereby causing the solvent (such as water) to move from a region of high solute concentration to a region of lower solute concentration.
The amount of osmotic pressure through a semipermeable membrane separating solutions of different concentration is given by
π = i×M×R×T
π = osmotic pressure
i = van't Hoff's factor
(M) = molar concentration
(T) = temperature in kelvin
R = ideal gas constant (0.08206 L atm mol⁻¹K⁻¹)
As seen above , the osmotic pressure is directly proportional to the concentration of the solution thus in the order of increasing osmotic pressure we have
- 0.7% KCl
- 1.5% KCl
- 1.8% KCl
- 5.0% KCl
- 8.6% KCl
The answer is D because one of them is sharing their electrons with the other.
Answer:
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. Hope this helps, mark as brainliest please!
