4 Ashleigh Stapleton June 18‚ 2012 Experiment 32: Identification of a Conjugated Diene from Eucalyptus oil Introduction In this experiment‚ the purpose was to prepare the Diels-Alder adduct of the unknown conjugated diene in Eucalyptus oil and determine the approximate percentage of diene in Eucalyptus oil. To discover the product of this reaction‚ isolate the adduct‚ and classify the diene from the melting point of its adduct. The unknown was one of four conjugated dienes.

The unknown soda ash from experiment 3 was used‚ to determine the weight for each trial we used the equation of (M of HCl) x (18 ml x 105.99) / (10 x 2 x Na2CO3 ). Which was equal to (0.01472 M) x ((18 mL X 105.99)(10 x 2 X 2.428 % )= 0.6 g. To start we had to rinse the beakers‚ electrode and the stirring bar with diluted water. The sample we needed was weighted to the closest 0.1 mg which we got was 0.3 for the first trial. The sample was transferred to a 250 mL beaker and dissolved in 70 mL of

Migrants of mixed-race origin - like Leila in The Final Passage‚ inherently suffered against racist attitudes in 1950’s Britain. In Black‚ white or mixed race? It is noted that: ‘mixed-bloods’ were seen as anomalies‚ demonstrably neither one race not another and as such they tended to arouse discomfort.’ This distaste for racial mixing was reflected in the derogatory names given by white people to those of mixed parentage such as ‘mulatto’ the Portuguese word for ‘mule’. The latter resulted in

3.1. Isolation and identification of Bacterial isolates An enrichment culture technique was used for the isolation of bacteria responsible for biodegradation of phorate in soil. Screening of these bacterial species for phorate degradation in liquid cultures in our previous study (Jariyal et al.‚ 2014)‚ resulted in identification of bacterial species B. aerophilus strain Imbl 4.1 ‚ Brevibacterium frigoritolerans strain Imbl 2.1 and Pseudomonas fulva strain Imbl 5.1. However‚ these bacterial species

I started out as an ignorant 7th grader who barely made AIME to a slightly less ignorant 8th grader who barely made USAJMO. In 7th grade‚ I did not even know what the nine-point circle was‚ and now in 8th grade‚ I am able to prove its existence. In 7th grade‚ I could not work with polynomials and roots very well‚ and now in 8th grade‚ I can use polynomials quite efficiently. In 7th grade‚ I failed the AMC 10 with a pathetic score of 123‚ and now in 8th grade‚ I was able to score well enough on the
