Membrane Functions: Aim: To demonstrate the process of osmosis using a chicken’s egg Hypothesis: I predict that the egg’s mass after 10 min. in the 5% salt solution would increase due to and balancing out the solution. In the 10% salt solution‚ the egg’s mass would decrease since there is a high amount of salt. In the dilute water solution‚ the egg’s mass will increase‚ as the membrane would take in that water. Materials: 1- One fresh egg 2- One plastic spoon 3- One plastic fork

Percent Yield = 8.29/12.51 x 100 = 66.27% Discussion: To produce t-Butyl Chloride from t-Butyl alcohol using hydrochloric acid‚ an SN1 type reaction is necessary. Optimal SN1 dehydration conditions require the reaction to take place in cool temperatures and in acidic conditions. SN1 type reactions have the fastest rate and the highest yield with tertiary alcohols. The first step of the SN1 type dehydration reaction is the protonation of the alcohol to form an alkyloxonium ion and free the halide

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks
