copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.

percent of iron in an unknown sample will be determined by using a redox titration and then compared to a different method. A primary standard which in this case is ferrous ammonium sulfate will be used to standardize potassium dichromate. The standardized potassium dichromate will then be used to titrate the unknown iron sample using the indicator p-diphenylamine sulfonate. The standardized potassium dichromate which has a concentration around 0.017 M is then titrated into the unknown iron sample

We all know Iron Man as the man in the red armor‚ yet we cease to know exactly what made the suit capable of it’s abilities. Nanotechnology is the prime reason behind Iron Man’s abilities in both the comic and movies. His suit actually contained little iron‚ in fact‚ the suit was “heavy‚ dense and prone to rust” (16). Thanks to Nanotechnology the suit was altered into something that would weigh less‚ be easier to maneuver in and prevent him from being injured during combat. As stated by Lynne Robinson

it applies to an isosceles triangle when it applies to a right triangle. He not only says the wrong triangle‚ he also gets the equation wrong. The Scarecrow says‚ “The sum of the square root of two sides of an isosceles triangle is equal to the square root of the third side.” The correct equation for the Pythagorean theorem is‚ “The sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.” The isosceles triangle is a triangle with at least two equal sides;
