Jonathan Sterling LAB REPORT RELATING MOLES TO COEFFICIENTS OF A CHEMICAL EQUATION PURPOSE Find the ratio of moles of a reactant to moles of a product of a chemical equation. Relate this ratio to the coefficients of these substances in the balanced equation for the reaction. DATA & CALCULATIONS DATA COLLECTED Variable Value mass of iron filings 2.24 g mass of paper towel 3.89 g mass of paper + copper 6.32 g visual observations dark, smells awful; opaque bottom layer, with a more transparent upper layer forming; purple-brown residue is on the sides of the beaker, and as the copper dust settles to the bottom, a metallic film is left on top. The bottom is now covered in reddish-brown precipitate, with a nasty greenish liquid on top. Table 1. The measurements taken for the Lab.
