Elemental Copper Mesh
1. If you began with .5296 g of copper mesh and recovered .2937 g of elemental copper, what would be the percent recovery of the copper metal? 55.45% 2. Describe the difference in the appearance of the copper mesh vs. the appearance of the elemental copper at the end of the reaction sequence. The elemental cooper was bright and gleaming while the copper mesh was more of a dark brown. They also had two vastly different textures, the texture of the copper mesh was grainy and the elemental cooper texture was slippery and smooth. The copper mesh also had bits and pieces of copper smashed together in small clumps and the elemental copper were strands of cooper entangled as a tightly packed ball. The elemental cooper was also more neatly packed

Penny Lab Report
463 Words | 2 PagesThe density of the penny was 4.68 g/cm3 before the experiment and 4.43 g/cm3 at the end of the experiment. The density of gold, though, is 19.3 g/cm3. Since the densities of the penny and the gold are different, the penny clearly did not change into another element. The gold color of the penny was a result of the flame that it was held above melting the zinc that it was coated in with the original bronze colored coating of the penny, creating an alloy with a shiny yellow color. Since neither of the pennies, silver colored or gold, changed densities throughout the experiment and each retained their own properties; the properties of copper; no new elements were
