Abstract on Determining the Photosynthetic Activity in Plants Using Different Wavelengths of Light using Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based

One interesting event from 1960 was the testing of the first atomic bomb by France. Between 1960 and 1966‚ seventeen bombs were tested by France. These bombs leaked radioactive materials that are still affecting citizens near the bomb sites in the Sahara Desert. It is estimated that hundreds of soldiers and nearly thirty million civilians were knowingly exposed to the radioactive areas. The bomb testings and radioactive exposure were reportedly meant to “study physiological and psychological effects

Determination of the relative atomic mass of lithium Introduction: For this investigation I will determine the Relative atomic mass (Ar) by using two different methods. In the first method I will dissolve a piece of lithium of a known mass in water‚ I will then collect the hydrogen gas produced‚ which can be used to calculate the relative atomic mass of Lithium. In the second method I will titrate the resulting solution of lithium hydroxide with a known concentration of hydrochloric acid‚ this
