CHE 242 Tutorial 3: Problems & Answers Week 4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a

William ‘Bill’ Shakespeare’s The Tragedy of Hamlet‚ King of Denmark‚ a turn of the 16th century revenge tragedy play‚ is today still a relevant and delving tale‚ that stands as Bill’s reconceptualization of the genre. The genre was popular at the time of Hamlet’s creation‚ and thereby retains traditional elements of a revenge tragedy. However‚ and after adding many dramatic elements‚ a flicker of an Oedipus complex‚ and a touch of humor‚ Bill analyses and explores the revenge tragedy on a more complex

Outline and Briefly Explain the Federal Court System The U.S. has a dual court structure. To be exact‚ we have a federal judiciary system and the systems that are operated by each of the states. This dual court structure is a unique feature of the American judicial system. Although most cases are tried in state courts‚ the federal court is playing a larger and larger role in finding resolutions to disputes. Partly‚ this is because congress in recent years has enacted a range of new laws that grant

Question: What Is the Importance of Chemistry? What is the importance of chemistry? Why would you want to learn about chemistry? Chemistry is the study of matter and its interactions with other matter and energy. Here’s a look at the importance of chemistry and why you should study it. Answer: Chemistry has a reputation for being a complicated and boring science‚ but for the most part‚ that reputation is undeserved. Fireworks and explosions are based on chemistry‚ so it’s definitely not a boring science

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the
