Four students have done a nice job drawing membrane models. Which model does the best job of showing osmosis? a. Thomas. Student

-drawn membrane model within a rectangular box. From left to right there is an upper and lower line spaced moderately apart. b. Three identical structures are dispersed across the lines consisting of a left and right apple-wedge shape with their flat ends facing across a narrow gap. c. Numerous orange dots fill the box above the structure, and three orange down-arrows are centered within each of the three gaps. d. The arrows start in the box near the orange dots and end in the space beneath the structure.

Answer:

The model that does the best job of showing osmosis is "Thomas. Student-drawn membrane model within a rectangular box. From left to right there is an upper and lower line spaced moderately apart."

Explanation:

Osmosis: this is a process of which molecules of a solvent pass through a semipermeable membrane from a lower concentrated solution into a more concentrated solution.

The minimum amount of energy needed to start a chemical reaction is known as:
nadya68 [22]

Answer:

The correct option is B. Activation energy

Explanation:

The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.

For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.

The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
