We are on an unceasing quest to find our own paragon of virtue. But what a treacherous thing it is to believe that a person is more than just a person! (John Green) The inherent thing in people is that we are fallible creatures. We have unfounded high self-esteem

Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate‚ CuSO4‚ mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was

STOICHIOMETRY The reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power •30 ml of CuSO₄

Manns 03/13/13 A Comparison of Iron Man 1 and Iron Man 2 Several superhero movies have been made but none have been as amazing and awesome as Iron Man 2‚ including Iron Man. The expectations of the first one were too high which made it hard for them to meet up to it. Since Iron Man failed at meeting its expectations the first time around‚ the expectations weren’t so high which made it easier for Iron Man 2 to meet it and surpass it. Iron Man 2 is much better than Iron Man because the setting‚ characters
