Social scientists have studied it‚ lawyers have tried to fix it and post-feminist society is over it. But women are still outnumbered by men in math‚ science and engineering fields. Most overt discrimination against women in the sciences has been reduced or eliminated in recent decades through legal‚ academic‚ corporate and government measures. But a climate that is less than fully friendly to women remains‚ and its texture is often still so taken for granted that it tends to be invisible. The

The crude product (aspirin) was purified in the last lab‚ using recrystallization‚ in which we dissolved the crude product with hot ethanol. We then added 25 mL of water until the product reformed (the solution became cloudy white) and redissolved the solid with hot ethanol. The solution was allowed to cool for a week‚ and crystals of purified solid were formed. In order to analyze this purified product‚ we determined the melting point by placing a small sample of the aspirin in a capillary tube

From what I observed is happening now‚ instead of being the country’s biggest hope‚ we seem to be one of its burdens. There’s pre-marital sex‚ prostitution‚ juvenile delinquencies‚ and the list

Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized

ANALYSIS OF ASPIRIN: SPECTROPHOTOMETRY The purpose of this experiment is to evaluate the percent aspirin on a commercial aspirin tablet using an instrumental method‚ spectrophotometry. In a spectrophotometer‚ light from a strong lamp passes through a monochromator‚ which breaks the light into its component colors using a grating‚ then uses mirrors and slits to direct a light beam of the desired wavelength through the sample compartment‚ where you place a tube (cuvette) of solution. A detector
