Experiment #1 Date: September 13‚ 2011 Title: Diffusion in Gases I Aim: To observe the diffusion of bromine Apparatus and Materials: Glass tube‚ bromine‚ fume chamber Diagram: Procedure: -Liquid bromine was placed in a jar and covered Observations: When first placed in the jar the original color of bromine was red-brown. As it began to diffuse its color changed from dark brown to a lighter brown until it becomes a yellow-like orange color. As it was diffusing liquid bromine changes its state

Explain how you would perform the role of Haemon during his interaction with Creon‚ in order to reveal his changing attitude(s) towards his father. The character Haemon appears on stage just as his Creon has deemed Antigone to her death as a punishment for a crime of family loyalty. In performing the role of Haemon‚ I would come onto centre stage in a costume of traditional Greek military attire adorned with royal crest of arms to portray his princely supremacy as a Theban prince. Creon’s costume

Introduction: The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times‚ a report released by the United Nations World Meteorological Organization (WMO) warns recently. Even if we managed to halt our greenhouse gas emissions today‚ and this is far from the case‚ they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate.

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

Experiment 4: Behavior of Gases Introduction: In this experiment‚ the problem trying to be solved is what gas laws are being used when the pressure‚ temperature‚ and volume are being measured. The three gas laws are Boyle’s Law‚ Charle’s Law‚ and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional‚ because when pressure goes up‚ volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and

The transition metals are placed in the centre of the periodic table‚ between groups 2 and 3. They are generally hard and dense‚ and less reactive than the alkali metals. Iron‚ copper‚ silver and gold are important transition metals. The transition metals: overview The elements in the centre of the periodic table‚ between groups 2 and 3‚ are called the transition metals. Most of the commonly used metals are there‚ including iron‚ copper‚ silver and gold The transition metals Common properties

Identify and explain how you would prepare for a health inspection. You may use some concepts learned from HACCP as an example. Personally‚ I would make sure that my restaurant or food service venue I was running is operating above expectations. First off‚ I would start with the overall appearance of the establishment. If a health Inspector was coming to review a fine dining establishment then it would throw off a lot of red flags if it didn’t look like a fine dining experience. I would have my employees

go on writing the intermezzo of your seventh symphony‚ but 20th century Russian composer Dmitri Shostakovich wasn’t your average man. He was despised by Stalin and the communist party‚ his music was original and adored by Russia‚ and he was known as the darling of the Soviet avant garde. In his music and his life‚ Shostakovich was a great risk taker‚ and never let any danger he was in affect his music. Dmitri Shostakovich took many risks‚ a myriad of which were in his music. In the early 1900’s

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and
