Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions

Concentration Camps in the Holocaust World War II brought many atrocities‚ 6 million to be precise (Wachsmann 2017). With so many camps not even discovered yet‚ as they are still doing an investigation into all of the locations of the camps‚ but we may not even know how many deaths and the torture of the prisoners by the Fuhrer and the Nazi’s. The Germans had many uses for the concentration camps. A concentration camp is a detention site outside the normal prison system created for military purposes

Concentration Camps Can you imagine being a Jew and living during the Holocaust? One day you are at your house doing your normal routine‚ and the next minute you are being loaded onto a cattle truck. You would be taken to the most horrible place imaginable. A concentration camp. A concentration camp was where people were kept without trial. They were kept in terrible conditions and had no rights. Concentration camps had forced labor‚ mistreatment‚ starvation‚ disease‚ and random executions. Concentration

A concentration camp was a prison where the many Jews‚ gypsies‚ homosexuals‚ disabled‚ Poles and Jehovah ’s Witnesses were sent by the Nazi regime. It is estimated that the Nazi party created and controlled 15‚000 different camps which were found in several countries. These countries included Germany‚ France‚ Holland‚ Norway‚ Poland‚ Russia‚ Yugoslavia‚ Austria‚ Belgium‚ Czechoslovakia‚ Finland‚ Italy‚ Latvia‚ Lithuania and Estonia. Most of the camps were constructed near railways which was mainly

supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater. This experiment aims to determine the effect of initial concentration and initial height of the slurry on its settling

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

Summary The basic memory mechanics exposes the power of concentration to improve memory. Concentrating can increase the amount of information encoded in the brain. Concentration enhances the basic memory mechanics by creating a healthy‚ vibrant and energetic brain. Combining basic memory mechanics
