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

HCl creates several colors‚ which are yellow‚ blue and green | F | NaOCl and KI | First a soft yellow‚ and after add the starch it changes to a black liquid. | G | KI and Pb(NO3)2 | It changes to a strong yellow liquid which seems to be more heavy. | H | NaOH and phenolphthalein | It gets a strong purple color | I | HCI and phenolphthalein | The change of the liquid from no-color to white shows that´s an acid‚ if it gets combines with a base like the number h the color became strong. | J

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

Lab 1: Flame Test 11 Chemistry‚ university Preparation Conducted: September 20th‚ 2010 Purpose: To observe‚ and create a chart of the colours produced when solutions of known metal compounds are heated to high temperature. Question: What colours are produced when different metallic compounds are placed in a flame‚ and why this happens? Hypothesis/Prediction: Different salts will produce different colours when placed in a flame‚ due to the fact that each element has a different

used to calculate heat transfer UA value and the effectiveness of the heat exchanger respectively. The report begins with the introduction into the experiment and gives a detailed account of the background behind heat exchangers and especially the shell and tube heat exchanger. This is followed by the list of objectives of the experiment‚ telling exactly what was expected from the laboratory and what information we wanted to gather from the experiment. The theory section explains the logic behind
