Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Candy Chromatography Background info: Paper chromatography is a logical technique used to separate works of a solution. Three examples of how we apply this technique to real-life would be: contaneminants in water‚ separation of plant pigmentation‚ and analysis of narcotics.

is the relationship between an increase in light intensity and photosynthetic rate in leaves from a corn plant? How does this relationship compare with what you observed for tomato plants? They both seem to be steady lines however in the corn leaf‚ it is a higher photosynthetic rate than in the tomato. Photosynthetic saturation is the maximum rate of photosynthesis. What value of light intensity produced photosynthetic saturation in corn leaves? You have to plot the O2 evolution and

The Last Leaf In his wonderful short-story The Last Leaf‚ O.Henry depicts a really admirable person - old Behrman. The story depicts the lives of artists in America at the turn of the 19th and 20th centuries.

ABSTRACT Separation and identification of components of a mixture was determined by using Chromatography. The components of a mixture have different affinities for a stationary phase as well as different affinities for a mobile phase. INTRODUCTION An extremely common technique by using two chemicals and filter paper can give you sufficient information. A well-done Chromatography of dyes will provide you with enough data to determine if a liquid mixture is heterogeneous or homogenous . In a learning
