Data Calculated from Experiment Solid-Liquid Weight (g) Solid-Liquid % Recovery Liquid-Liquid Weight (g) Liquid-Liquid % Recovery Acid 0.01 20 % 0.028 56 % Phenol 0.011 22 % 0.001 2 % Amine 0.013 26 % 0.005 10 % Neutral 0.03 60 % 0.026 52 % Table 1 shows the data obtained from this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the…

value of the flux density B at that point in a magnetic field. Therefore the flux density is the cause while the flux density (B) is the effect. The flux density can be assumed proportionally to the field intensity in a magnetic field which comes in three parts. First part is: Where U stands for the permeability of force (the measure of the degree to which the magnetic line of force can penetrate the material). The value of magnetic space constant is B is the magnetic flux density while H…

Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

A water table marks the top of the saturated zone of groundwater. When something is saturated, it means one substance (Like soil) is filled with another substance (Like water). Therefore, the area filled with water is called the saturated zone. This zone can be called the phreatic zone or the zone of saturation. This is always the zone below the water table. Directly above a water table there is always a capillary fringe. The water table separates the capillary fringe from the zone of saturation…

This Density of Copper lab was an experiment, which helped to show how to calculate the density of copper while comparing the results of the density of water. While doing this experiment we had to remember the density of water, which is 1g/cm3. However, before trying to find the density we needed to make sure we had the mass and volume. We were given two ways to help find the density of copper and a beaker. I had to first measure the mass of the copper by picking it up and gently placing it in…

water, hexane and ethyl alcohol. Also, its density and boiling point were obtained and compared to the theoretical values. Theory Chemical substances can be identified through investigation of their chemical and physical properties and then comparing the experimental values to the standard values. Physical properties do not change the chemical composition of the substance. Physical properties include; density, boiling point, and solubility, etc. The density of a substance is the ratio of the…

examples of density dependent factors. DESCRIBE how density dependent factors affect the size of a population. ANSWER: Density dependent factors could be food, water, and shelter. Density-dependent factors affect the size of the population because if there was not enough food, water, or shelter for the increasing population, the population will begin to level off until they hit its carrying capacity point. 3. IDENTIFY TWO examples of density independent factors. DESCRIBE how density…

convincing the people who were hiring, to giving him the job. Doing so he had jumped into a cab, solved a rubix cube, and most importantly ran away from the cab driver for not having enough money to pay him, which then leads to him losing another “Bone Density Scanner”. Another reason Chris is hardworking and determined, is that he would stay up late, studying for a test/ to get a job as a stockbroker, and even more so on trying to fix his machine. Finally, during Chris’ internship, he had…

population size that can be supported by the resources available in the environment. Once an environment has reached this maximum capacity in regards to the resources, the population growth oscillates around the environment's carrying capacity. Density-dependent regulations mostly occur when there is a limited about of food or other resources available to the population. This creates an environment where the population is forced to compete for the resources, or the environment is so dense with…
