process‚ three calculations were done to find an average. This experiment is vital to the success of the following two thermochemistry experiments. The second experiment‚ entitled Hess’s Law‚ is a simple confirmation of said law. To do so‚ we take three reactions‚ where one of them is the same as the other two‚ and measure the heats of reaction for each of them. Hess’s Law states that the heat of reaction of the one reaction should equal to the sum of the heats of reaction for the other two. The three

In this local experiment‚ the goal was to use a polyacrylonitrile (PAN‚ (C3H3N)n) in addition to a chalcogel. This chalcogel is efficient at adsorbing I2 gas. Although just the chalcogel itself isn’t mechanically stable especially if it is to be used in the field for actual radioactive iodine capture. By creating a hybrid substance with the PAN and the chalcogel in a mixture‚ the theory is that they can create a mechanically stable efficient iodine capture method. This experiment did not study the

B) What does the word “freedom” reminds you of? How would you define freedom? O) Everything can be defined with its opponent‚ therefore captivity comes to my mind when I think of freedom. Being behind walls is not the only thing that captivity reminds me of. Actually everything that limits us in our daily lives‚ everything that restricts our lives can be considered as something that captures us. Therefore a world without those can be considered as a free world‚ though it cannot be fully possible

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

hope that you give the neighborhood watch program the attention it deserves so that it may advance‚ and perform it’s services to the best of it’s ability. Distributing flyers by placing them in mailboxes would better advertise the program‚ or possibly mentioning the system at the end of the township meetings. There are many simple ways to spread the word about Pittsgrove’s neighborhood watch. I am personally willing to assist with publicizing the organization in any way necessary. Thank you for your

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average
