Name ____________________________ Date ____________ THE EFFECT OF CONCENTRATION ON THE RATE OF DIFFUSION PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient‚ (2) To explain experimental data concerning different concentration gradients‚ (3) To complete a data table and prepare a graph to illustrate the data‚ and (4) To apply information from

How to Unblock Fallopian Tubes Overview Blocked fallopian tubes? Then you need to worry not‚ there is hope.40% of women with infertility get it from blocked fallopian tubes. Before reading on you should have had a hysterosalpingram test (HSG) with your doctor to confirm that the cause of your infertility is blocked fallopian tubes. Over the years women have had blocked fallopian tubes unblocked rekindling the joy of ever having children. All you need is following the given instructions to the later

Fire tube boiler designing Fire tube boilers operate by sending combustion/flue gas by using a combination of straight tubes flanked by trouble held in identical vessel. Often identified by the variety of passes used (say for example a 3-pass or 4-pass fire tube boiler)‚ this refers to the variety of times combustion gas flows the capacity of the pressure vessel mainly because it transfers heat on the water. A wet-back fire tube boiler utilizes a water cooled publish zone (end closure). A dry-back

endotracheal tube you will prefer RAE‚ flexomettalic or mcintosh? What are the problems associated with these tubes? Ans- Ideal ET Tube is south facing RAE (Ring Adair Elwin) tube fixed in center over the lower lip. RAE Endotracheal Tubes are designed to conveniently position the anesthesia circuit out of the surgical field. Problem- Difficult to pass Suction catheter. Fixed curvature hence more chances of endobronchial intubation or inadvertent extubation. Flexometallic tubes- Inner diameter of tube decreases

discuss how concentration ratios are used to determine total market shares within four specific industries. I will also discuss the levels of competition within those industries and how oligopolies can benefit society. Case‚ Fare‚ and Oster defines concentration ratio as the share of industry output in sales or employment accounted for by the top firms (2009). They are used to measure the total output produced by a certain number of firms within an industry. Four-firm concentration ratios

Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance

the iodine solution titrant‚ exactly 50 mL of 0.01 M KIO3‚ exactly 20 mL of 10% KI solution‚ and exactly 25 mL of 0.3 M H2SO4 was transferred into a 100 mL volumetric flask using a volumetric pipette. The volumetric flask was then filled to the mark with distilled water. The flask was covered with Parafilm and inverted to mix. The next part of the experiment was to determine the Vitamin C in a solution of known concentration. Observations of the Vitamin C sample and the amount found on the label was

BOURDON TUBE PRESSURE GAUGE Bourdon Tubes are known for its very high range of differential pressure measurement in the range of almost 100‚000 psi (700 MPa). It is an elastic type pressure transducer. The device was invented by Eugene Bourdon in the year 1849. The basic idea behind the device is that‚ cross-sectional tubing when deformed in any way will tend to regain its circular form under the action of pressure. The bourdon pressure gauges used today have a slight elliptical cross-section and

I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane.
