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

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;

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
