Glory, a 1989 film directed by Edward Zwick, tells the story of the 54th Massachusetts Volunteer Infantry, one of the first all-black regiments to fight in the American Civil War. The film follows the journey of the regiment, from their initial recruitment and training to their eventual deployment in the war, and focuses on the experiences of several key characters, including the regiment's white commander, Colonel Robert Shaw, and several of its black soldiers, including Trip, a runaway slave, and John Rawlins, a former servant.

Throughout the film, the theme of glory and the various ways in which it is understood and pursued by the characters is a central and driving force. For the white officers and politicians who encourage the creation of the 54th Massachusetts, the prospect of sending black soldiers into battle is seen as a way to prove their worth and earn the respect and admiration of their white counterparts. For the black soldiers themselves, the opportunity to fight for their freedom and the freedom of their fellow African Americans is a source of pride and a chance to claim their own sense of glory.

However, as the film progresses, it becomes clear that the pursuit of glory is not always straightforward or without cost. The soldiers of the 54th Massachusetts face significant challenges and hardships, including discrimination, prejudice, and the dangers of war. They are also faced with moral dilemmas, as they struggle with the weight of the expectations placed on them and the sacrifices they must make in order to achieve their goals.

One of the key themes in Glory is the idea that true glory is not always about achieving fame or recognition, but rather about standing up for what one believes in and making a difference in the world. This is exemplified by the character of Colonel Shaw, who initially joins the regiment as a way to redeem his family's honor, but comes to understand that true glory lies in his commitment to his men and their cause. Similarly, the character of Trip, who initially resists the idea of fighting in the war, ultimately finds glory in his willingness to stand up for what he believes in and fight for his own freedom.

In conclusion, Glory is a powerful and thought-provoking film that explores the theme of glory and the various ways in which it is understood and pursued by its characters. Through its portrayal of the struggles and triumphs of the 54th Massachusetts, the film highlights the importance of standing up for one's beliefs and the power of ordinary people to make a difference in the world.

Once filtered, the product will be purified using recrystallization and the melting point will be identified. Please do not ask for help acquiring, preparing, or handling illicit substances or for help with any activity that does not fall within the confines of whatever laws apply to your particular location. Again all those pictures are fisher? Please complete any questions as much as you can before posting. Each product consists of a different mechanism. If so then the top left and right images is erythro syn only correct? We will not do your homework for you, so don't ask.

. The results indicate that the melting point range of the product was between 100 degrees celsius and 120 degrees celsius. Any help is appreciated to get me started! It is also important that you describe the specific part of the problem you are struggling with. Bonus points: If submitting a picture please make sure that it is clear. In order to determine the mechanism, a solution of bromine in acetic acid will be added to a solution of trans-cinnamic acid to be separated using vacuum filtration. Now first question is in the title of this post, so do let me know!

Lab Report 2

erythro 2 3 dibromo 3 phenylpropanoic acid

As a result of the melting point is erythron-2,3-dibromo-3-phenylpropanoic acid this means that the mechanism that occured was a result of anti-addition of bromine. Here are three possible products for the addition of bromine to trans-cinnamic acid: erythro-dibromide, threo-dibromide or a mixture of both. Sealed in dry,Room Temperature solubility soluble in Methanol form powder to crystal pka 2. The melting point of the product will be used to determine which of the three possible products is produced. This could have been a result of the product being left in the flask or errors during the recrystallization process.

Again using same product, 2,3-dibromo-3-phenylpropanoic acid? And the bottom left and right pictures is threo anti only correct? A screenshot is preferable to a picture of your laptop screen. Again we are being asked to draw the structure for syn, anti and a mixture of both. Any infractions will be met with a temporary ban at the first instance and a permanent ban if there is another. Melting point range: 100-120 C Discussion: The main purpose of this experiment was to determine the product produced from the addition of bromine to trans-cinnamic acid and measure the melting points. Conclusion: The results of this experiment concluded that the addition of bromine of trans-cinnamic acid underwent an anti-addition mechanism. General Description Dehydrobromination of α,β-dibromohydrocinnamic acid has been studied in liquid ammonia.

It is OK if you are a little or a lot! Anti-addition mechanism yields erythron 2,3-dibromo-3-phenylpropanoic acid, syn addition yields thero-2-3-dibromo-3-phenylpropanoic acid, and non-stereoselective mechanism which yields a mixture of both erythro and theo products. Second question is how the heck do you draw a mixture of both erythro and dibromo in the same structure? Although the percent yield of the experiment was 77%, meaning 22% of the product was lost. Please flair yourself and read over the rules below before posting. And also draw the structure if I have a mixture of both. Also what would a mixture of syn and anti look like? Based upon the melting point, the mechanism produced erythron-2,3-dibromo-3-phenylpropanoic acid.
