Why do herbaceous plants wilt when they do not have enough water and stand erect when they have water?
This relates to the type of solution the plant cells are exposed to. In general, there are 3 distinct types of solutions in nature: hypotonic, isotonic, and hypertonic. A hypotonic solution is one that has a low concentration of a solute relative to the solute concentration inside the cell, such as distilled water. An isotonic solution has the same solute concentration as the inside of the cell. A hypertonic solution has a higher concentration of solute than the inside of the cell.Back to the plants...When plants wilt, that means the are exposed to an isotonic solution. When this happens, the net amount of water moving between cells and the environment is equal. As a result, the cell becomes flaccid and the plant wilts.When plants stand erect, this is a result of turgor pressure. When in a hypotonic solution, such as distilled water, the plant cells absorb the water and store it in its central vacuole. The cell cytoplasm enlarges and pushes up against the sturdy cell walls. This cell is said to be turgid, or stable.
What does concentration mean in chemistry?
Concentration relates the amount of solute to the amount of solvent. For instance, in a salt water solution, salt is the solute and water is the solvent. A way to measure the concentration of a chemical would be molarity or M. The molarity stands for the moles of solute in the liters of solvent.
What is the collision theory and how does it relates to reaction rates?
it depends on how high or low the reactant is on the temperature.
What element of the CRAAP test relates to timeliness?
element of the CRAAP test relates to timeliness
How do you define Kinetic Theory of Diffusion?
From what I know, Kinetic theory of diffusion is the movement of particles in a closed environment from a region of high concentration or pressure to a low concentration or pressure conditions. Diffusion is mainly controlled by the kinetic energy of particles which further relates to their states they are in whether gas, liquid or solid. The more spaced out they are, the more freedom they have to move around and bombard to each other and generate kinetic energy.
What is rate laws?
An equation that relates the reaction rate to the concentration of the reactants
The expression that relates emf potential current and resistance is Ohm's law?
Yes, that is what it is called.
In a concentration cell with the same metal in each side does concentration of a metal ion affect voltage?
Yes. The Nernst equation relates the concentration in each cell to the voltage. Consult http://en.wikipedia.org/wiki/Nernst_equation

Why is the pH scale 1-14 and not 1-10 or something more intuitive?
The pH scale relates to the acidity (or otherwise) of a solution, & what determines how acidic a solution is is the concentration of hydrogen ions the solution contains. I forget the details of how or why, but it was worked out that the difference in hydrogen ion concentrations in typical solutions could vary by a factor of 1014, and that in a neutral solution the hydrogen ion concentration is 1.0 x 10-7, with more acidic solutions going up to a concentration of 1.0 x 10-1 and more basic solutions going down to 1.0 x 10-13. But these figures are quite a mouthful to either say or write, and so the pH scale was introduced; remembering that 1.0 x 10-7 was the neutral concentration, 7 was put in the middle of the scale, with the figures going up & down on either side.
