Thousands of people across the world dye their hair; dating back all the way to 3400 B.C. when “people used extracts from plants or minerals that contained pigments like those of henna or black walnut shells”("History & Future Discovery of Hair Dye."). In 1932‚ hair dye was refined to create chemical reactions in the hair to change the natural structure and color of hair. Cosmetologists are near a plethora of chemicals every day that include carcinogens and mutagens they would never suspect

Purpose: The purpose of this lab is to find the amount of blue dye #1 in the blueberry pomegranate gatorade. Procedure: We created dilutions using stock solution(10mL stock/0 mL water‚ 8mL/2mL‚ 6mL/4mL‚4mL/6mL‚ 3mL/7mL‚ 2mL/8mL‚1mL/9mL‚ 0mL/0mL). Before we put each dilution in the SPEC 20‚ we put water in a cuvette and put it in the SPEC 20 so we could zero out the percent transmittance. We collected the percent transmittance of each dilution using the SPEC20 with a wavelength of 630nm.

Analysis 1. Examine the structures of the FD&C Red No. 40‚ Blue No. 1 and Yellow No. 5 dyes. What are the similarities and differences in the structures of the three dyes? a. Red No. 40‚ Blue No. 1‚ Yellow No. 5 contain carbon rings and NaSO3. Additionally‚ Red No. 40 and Yellow No. 5 are very similar‚ as they both contain one nitrogen double bond‚ a hydroxyl group‚ and no ions. Blue No.1 contains nitrogen and chlorine ions and N(C2H5)CH2. 2. In the Introductory Activity‚ the developing solvents

Multicultural Education Scenario Steps required for multicultural education to be effective are trust‚ tolerance‚ understanding‚ and open mindedness. The most important step is gaining the trust of pupils by including the culture of all its students (Johnson‚ Musial‚ Hall‚ Gollnick‚ & Dupuis‚ 2005‚ p. 121). All students have to be taught tolerance for each others abilities‚ limitations‚ and differences. By understanding the cultural differences in all of us‚ we can learn to understand each other
