The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending on certain factors. Temperature‚ pressure‚ and surface area all affect the dissolving process. Increasing the pressure causes the solute to be increased in the solvent

manipulating the concentration and weight percent of the active metal. 36 5.2 Conclusion In this research‚ the objective are to determine the effect of concentration of KOH to yield of FAME and also to determine the effect of KOH weight percent as loading metal in OPKS support. From the result shown in previous chapter‚ we can see the trend of graph for each parameter which is yield of FAME increase if concentration of KOH/weight percent of KOH increase. The best KOH concentration that gives the

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

Cu(IO3)2 (s) [ ][ [ [ A: [ ( Q: ) ] ][ ][ ] ] What is the equilibrium concentration of Cd2+ ions in a saturated solution made by shaking CdS(s) with water? Ksp = 6.0x10-27 for CdS. [ 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

mechanism behind this theory is based on the reference on the visible light spectrum. Different compounds absorb different wavelengths of light and appear to be the colour that it’s reflected which can be observed with our naked eyes. The higher the concentration of the absorbing compounds in a solution‚ the greater the amount of light that is absorbed. The absorbance of a solution can be determined using the methods as follows: 1) Transmittance‚ T is the amount of light transmitted through a solution

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

Yeats Fermentation Lab Investigative Question: How does the sugar concentration affect the fermentation of yeast? Hypothesis: The percentage of sugar in a solution is directly proportional to the amount of produced CO2‚ as a result of Yeast fermentation. Data table: Amount of CO2 measured in cm.
