Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction between an unknown ester and water

Cardinal Principles of lending: A bank is an institution which is primarily seen as a body that accepts monetary deposits from its customers (general public)‚ looks after their money‚ offer them some beneficial services such as cheque books to make payments and lends money to other public (borrowers). Now lending money to someone comes with some inherent risks especially when a bank uses its depositors’ money to lend. To put it simply a bank’s major operation is to borrow money from depositors and

sodium bicarbonate or baking soda is combined with moisture and an acid (like yogurt‚ chocolate‚ buttermilk‚ honey‚ etc.) and this results in a chemical reaction that produces carbon dioxide‚ or CO2 ‚ bubbles that start to expand under higher temperatures‚ like inside an oven‚ causing baked goods to rise. This process is an almost instant reaction when the ingredients are mixed together. If a Baking recipe calls for baking soda‚ it needs to be baked immediately‚ or else they will fall flat!

Diels-Alder cycloaddition reaction was discovered by Otto Diels and Kurt Alder and is very useful in the synthesis of polycyclic compounds. The Diels-Alder reaction can be described as: [4+2] cycloaddition- a diene with 4 π electrons + 2π electrons from the dienophile; a pericyclic concerted reaction- meaning the reaction occurs in a single step (no intermediates) and involves a cyclic redistribution of bonding electrons. In order for a Diels-Alder reaction to take place the diene must

lacks love and affection. Julia feels silly and ridiculed by Bertrand and does not understand why he chooses to act this way. However‚ in the movie Antoine is not in this scene and their relationship is strong and is working well. As well‚ later on dans le roman‚ Julia finds out she is pregnant and thinks Bertrand will be happy to know this. After telling him‚ she finds out that he is not happy she is devasted and this can be seen when she says >(156-166). This quote shows how terrible and angry Julia
