Webb7 okt. 2024 · Scientists generally define a molecule as organic when it contains not only carbon, but also at least one other element. Typically, that element is hydrogen, oxygen, nitrogen or sulfur. Some definitions say that a molecule must contain both carbon and hydrogen to be organic.

WebbIn your lab report, determine if the dye is in the aqueous, organic or both layers. 2. In a test tube were combined ~1 mL of diethyl ether, ~2 mL of distilled water, and a few drops of 0.006 M methyl red. The test tube was capped and mixed vigorously for 10 seconds. The layers were allowed to settle, and a picture of the test tube was taken. WebbThe layers were separated and the aqueous layer was extracted with CH 2 Cl 2 (3 x 3 mL). The combined organic layers were washed with H 2 O (3 x 5 mL) and brine (10 mL), dried over Na 2 SO 4, filtered, and concentrated. Purification by flash column chromatography affords the corresponding N-heterocycle. laya healthcare providerWebbVegetation and soil (organic and mineral layers) water content were determined using the oven drying method. For the soil samples, we used a drying temperature of 85 °C for a period of 48 h. This temperature was used in order to avoid charring of the organic fraction, which may occur at the standard drying temperature of 105 °C . laya healthcare prime plan
