strategy. The first part of Porter’s Five-Force model is rivalry. According to Porter‚ rivalry focuses on two main factors which are a high concentration ratio and a low concentration ratio. A high concentration ratio indicates that a high concentration of market share is held by the largest firms which the industry is concentrated. A low concentration ratio indicates that the industry is characterized by many rivals‚ none of which has a significant market share (Porter‚ 2010). Porter offers

[ A: [ Q: ][ ] ][ ] ; ][ ] √ √ A solution in equilibrium with a precipitate of AgCl was found to contain 3.4x10-6M Cl . Calculate Ksp for AgCl. [ ( A: [ ][ ] ; ][ ] ) Q: Since the value of Ksp depends on the concentrations of the ions in solution‚ a larger value of Ksp indicates a more soluble salt

Title: Diffusion Rate of Methylene Blue on Agar Plates at Different Temperatures Abstract: Diffusion is the movement of particles from an area of high concentration to an area of low concentration wherein substances are independent‚ rapid and in random motion which frequently collide with each other in the sides of the container. This study aimed to assess the influence of temperature on the diffusion rate of methylene blue on agar plates. To determine the relationship between the two variables

supported the hypothesis that if Daphnia are placed in differently concentrated solutions of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of calcium chloride‚ one or

and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution‚ volumetric analysis was used. In volumetric analysis‚ a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4.‚ also known

Osmotic concentration‚ formerly known as osmolarity‚[1] is the measure of solute concentration‚ defined as the number of osmoles (Osm) of solute per litre (L) of solution (osmol/L or Osm/L). The osmolarity of a solution is usually expressed as Osm/L (pronounced "osmolar")‚ in the same way that the molarity of a solution is expressed as "M" (pronounced "molar"). Whereas molarity measures the number of moles of solute per unit volume of solution‚ osmolarity measures the number of osmoles of solute
