Organic Chemistry Lab EXPERIMENT #2 and #3 Extraction and Evaporation Recrystallization and Melting Point Measurement PURPOSE: 1. To the components of a simulated pharmaceutical preparation‚ Panacetin‚ and identifying the unknown component of the mixture through extraction and separation methods. 2. To learn how to purify by recrystallization‚ how to dry them and how to obtain a melting point. PRECAUTION: ACETANILIDE AND PHENACETIN ARE EYE AND SKIN IRRITANTS. Minimize contact with

English 11 America is the land of opportunity‚ so they say; but a country is made up of more than just opportunity. The land itself is made up of mountains‚ trees‚ lakes‚ and buildings.

Melting Permafrost’s Negative Contribution to Global Warming [pic] Global Warming is a problem that impacts the entire planet. The average temperature of our planet has risen about 0.5°C in the last 100 years. According to field biologist Wolter in 2008‚ the melting of permafrost in the colder regions of the world is mostly responsible for global warming; causing the world’s climate to be at risk. (Wolter‚ 2008) “Permafrost is any rock or soil that remains frozen constantly

weighings. This procedure was repeated two more times and the average of the three measurements was recorded as the density. The boiling point was measured using a microscale device consisting of a capillary tube‚ a microcapillary tube and a melting point apparatus. The microcapillary tube was sealed on one end by rotating the end gently in a Bunsen burner flame until it was sealed. Care was taken to avoid overheating the tube which would cause it to bend. The larger capillary tube was heated
