In The Tragedy of Julius Caesar‚ by William Shakespeare‚ Brutus is the tragic hero for many reasons. Brutus’ character is noble‚ loyal‚ and honest. In the play Brutus is forced to make a difficult choice between killing Caesar‚ the ruler of Rome‚ to save Rome or to stay loyal to Caesar and let him live. Even when he stabs Caesar he is noble because he was doing it for the citizens of Rome. One of the reasons that Brutus is a tragic hero‚ is that he is very hesitant about killing Caesar. He has

Courtney Ulrick Lab Experiment #4 Properties of Gases Purpose: The purpose of this experiment was to understand the gases; Hydrogen‚ Oxygen‚ and Carbon Dioxide. The experiment helped me understand the properties of these gases‚ specifically their physical and chemical properties. Data: Gas | Flame Reaction | Glowing Splint | Limewater Reaction | Bromothymol Blue Reaction | Hydrogen | Loud Pop | | | | Oxygen | | Glowing Brighter | | | Hydrogen & Oxygen | Loud Pop‚ extinguished

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict

General Chemistry 1 Lab 4 Properties of Gases LabPaq - Properties of gases General Chemistry Introduction Background This report covers Properties of Gases and will allow me the opportunity to explore chemical and physical properties of gases. Collection and use of these gases will also be conducted in this lab. Statement of Problem Collecting gases is a difficult process. Singling out a gas and obtaining only that gas is the challenge we face in this experiment. Purpose

neutralizing alkalis‚ and dissolving some metals. It can be corrosive or it can be sour liquid of this kind. Acids are also all around us in everyday life‚ for example‚ carbon dioxide gas dissolves in rain to form carbonic acid (a weak acid). We find acids in many foods‚ such as ethanoic acid in vinegar. These acids are not hazardous. Some acids‚ which are found in the laboratory a car battery are too dangerous to taste or touch. Another name of these acids are strong acids. Alkalis are substances

In the medieval period the most powerful people in the Western Europe were the great nobles kings‚ lords and the lesser nobles. They were at the top of the feudal system.Nobles had control over the knights and peasants. Kings and queens found it difficult to rule without the help of the nobles for three main reasons. Firstly they needed the force of fighting men (knights) on call if their power was threatened‚ Secondly they needed someone to travel their messages it was hard for rulers to make their

Study of Gold metal Date: 14/01/2013 Submitted to: Dr Sami Habib Submitted by: Jamil Mahfoud (A1010659) I- General introduction about metals: a- Historical background Back to 6000 BC‚ process metallurgy is known as one of the oldest applied sciences. Despite that the form of metals was very basic but it has a big impact on the society because of its wide uses especially as tools for agriculture or hunting and even as artistic styles later on. There are 86 known metals so far that were

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements
