spaces between the fibres of the chromatographic strip. So‚ this technique is very sensitive laboratory tool since it can differentiate existence pigments in a plant based on the molecular structure of the pigments. From the experiment results‚ the Carotenoid has the lightest molecular weight. Its ratio of front is less than chlorophyll b‚ meaning that it can cause more raise between the microscopic spaces between the fibres of chromatographic strip. There is correlation between molecular weight and

Nicole Mintz‚ Bayla Kronman and Dvora Feinblum ABSTRACT This experiment will enable us to separate the pigments of a plant by using the method of paper chromatography. Thanks to this technique the pigments were painted on the strip of paper‚ and we were able to calculate the distance each of them went up: the Rf value. We saw that carotene went the farther up and that chlorophyll ’a’ stayed next to the bottom part of the paper. Because the pigments have specific characteristic

destination point for human traffickers‚ a conservative estimate states that approximately 800 people are trafficked into Canada annually. These people (mostly women and children) are transported into Canada illegally and harboured into bawdy houses and strip clubs across the country. Many of those who are trafficked come from Latin American countries‚ where the incredible poverty drives many into extreme circumstances where they may fall victim to the promises of economic freedom in the developed world

Taking care not to damage the white‚ powdery stationary phase‚ use a #2 pencil to draw a line across the width of the strip. Carefully mark two evenly spaced spots along the line to delineate where to spot the dye solution. 2. The TLC strip can now be spotted. Use the capillary tube to apply two dots of the dye onto the TLC strip as in the figure 1 below. 3. Transfer enough solvent into a 200 mL beaker

For example‚ if the length of the finished tutu will be 20 inches (50 cm)‚ cut the tulle into strips 41.5 inches (105 cm) and 3 inches wide. STEP 5. Attach the tulle to the elastic band. Fold the tulle strips over the elastic. Stitch the front of the strip to the back piece with a sewing machine. Do this for all the tulle strips‚ until the circle is complete. STEP 6. Check the fit.

1. In the excel worksheet‚ we combined the 12% non-callable bond maturing in May 05 and the zero coupon STRIPS with the same maturity to get a synthetic bond with semiannual interest payments of $4.125 per $100 par value. The ask and bid prices of the synthetic bond are calculated to be $98.78 and $98.53. Alternatively‚ we combined the non-callable bond maturing in 2000 and the STRIPS 00 to get a synthetic bond to match the callable bond if it was called at the first possible date. The ask and

Red and yellow are the two brightest colors used in the strip. Red is also a color known to cause a physical reaction within the human body. I believe the creator uses these two colors to highlight the most important points throughout the cartoon. For example‚ there is a large red stop sign with “STOP ILLEGAL

In the Dreamscapes film the content was stronger than the Strip Mall trilogy. Because there was a story based around the pictures‚ than just letters thrown on a screen.

In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include
