Chemistry - Module 2 - Metal 1. Metals have been extracted and used for many thousands of years * Outline and examine some uses of different metals through history‚ including contemporary uses‚ as uncombined metals or as alloys. Contemporary Uses of common metals Metal | Uses | Iron and Steel (an alloy with <2% carbon)Good tensile strength‚ cheap‚ rusts (corrodes) | - Railways‚ bridges‚ buildings- motor cars bodies‚ ships and trains- Engine blocks‚ fire hydrants‚ drainage

Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more electropositive metal will displace the less

Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals

The Scholarship Jacket Racism is a well known problem throughout this world. We get judge every day whether its our race‚ the way we dress‚ the way we talk‚ how we do academically‚ and if were going to succeed in life based on others people way of thinking what success is. The following story that I read is an excellent example of the way people underestimate us just because of our race or where we stand in society. “The Scholarship Jacket” by Marta Salinas is about a young girl wanting to figure

that gives the chemicals color. A change in the pigments will cause the light to reflect differently and a color change to occur. Testing for pH is an example of a color changing reaction. The pH of the solution will change the pigment on the litmus paper or in the indicator. Acids and bases change the pigments in different ways‚ which causes the indicator to change different colors depending on the pH. A precipitate is formed: A chemical reaction has occurred if two liquids are poured together

Plutonium Essay I would like to work on the metal plutonium because the discovery of plutonium has a great impact on the world. Plutonium’s symbol is Pu and its atomic number is 94. This element has 150 neutrons and 94 protons and its standard atomic weigh is 244. Plutonium is located in the 7th period and it is a silvery white metal. One of its main uses is to act as the fuel of nuclear fission Plutonium does not exist naturally‚ although some say that small
