colour because of the sulphuric acid but during the leaching process‚ the copper was dissolved into the sulphuric acid giving it its blue colour. During the cementation process‚ the copper was replaces with the iron as it was more reactive‚ therefore the copper swapped places with the iron‚ as shown by the brown colour and then the solution became clear

Hypothesis: I predict that air (oxygen) and water are necessary for iron to rust. The nail in water with air will rust while the nails in dry air and in boiled water with no air will not. I also predict that galvanizing the nail with zinc and greasing the nail and painting the nail and electroplating the nail will inhibit rusting. I also predict that adding NaCl to the test tube with water and air will promote rusting of the iron nail. Background information: Rusting is the chemical reaction between

Blacksmith has two word parts. Black comes from the color of metal that they shape. After the iron ore is smelted into iron‚ the iron is black. Smith comes from the word smite. Smite means to strike hard with a hand or a weapon. Blacksmiths use hammer to “smite” the metal. Blacksmiths had a very important job‚ as they had to create different tools for other people. Tools How did the Blacksmith make iron ore into usable products? He had lots of tools to help him (see picture below). To heat and give

Sometimes granular pellets are used instead of crude ore. Blast furnace consists of five constructive elements: top cylindrical part is top throat‚ that is necessary for the charging and distribution of burden in furnace; the highest splayed conic part is shaft‚ where the heating process of materials and the reducing of iron from oxides pass;

Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases

involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze the products and use the data to determine the true amount of iron in each product‚ as well as confirm that the iron was usable by the human body

This simply means that the sum of the areas of the two squares formed along the two small sides of a right angled triangle equals the area of the square formed along the longest. Let a‚ b‚ and c be the three sides of a right angled triangle. To define‚ a right angled triangle is a triangle in which any one of the angles is equal to 90 degrees. The longest side of the right angled triangle is called the ’hypotenuse ’. Once you have this basic understanding you can apply the understanding that if a
