Hello, these are part of one question, please show work.

Data Sheet Chemical Reactions 2. Obtain and clean with sandpaper to expose the surface: 3 pieces of zine, 2 pieces of copper and 1 piece of lead. Place 6 test tubes in a rack and label each appropriately. Observe the contents of each of the test tubes for evidence of a reaction. Record your observations in the tables below TABLE 55 Observations Tube I: Copper strip and approximately 1 mL silver nitrate 09-7XN Copper urned into haki COD and formed different shape it was fluffy Reactants Products Balanced Chemical Equation Total lonic Equation Net lonie Equation Which element is oxidized? Which element is reduced? Which element is more active? Which element is less active? TABLE 9.10 Observations Tube 2: Lead strip and about 4 mL copper(II) nitrate Zinc Strip turned black Reactants Products Balanced Chemical Equation Total Ionic Equation Net Ionic Equation Which element is oxidized? Which element is reduced? Which element is more active? Which element is less active?

Answer 1

DAAR лас 4me Table 9i9 copper strip and approximately 4 me. silver nitrate. observation: when a strip of copper metal is released in silver nitrate solution, copper displaces silver from its compound by forming copper nitrate with a shiny Copper greyish white deposit of silver on the strip.

2 27 The reaction is shown below- 2 Ag NO3 + ce cu(NO3 + Ag (Hilver nitrate) (copper strip) (copper nitrate) (silver) Reactants: 2 AgNO3 + cu Products: Cu(NO3) + Aq Balanced chemical equation : 2 Ag NO3 + ca - ae (NO3)2 + 2Ag Total ionic equation 217109) +QNOZ (aq) + Cu(s) —cube) tano.(62) + 2 Agos) Net ionic equation : Cu(s) + 2 Ag+ (aq) - cu²tlag) + 2 Ag ) element which is oxidised copper (Cu) element which is reduced silver (Ag) element which is more active copper (4) element which is less active Silver (Ag) Note UUUUUUU --> Cu2+ + 2e- Oxidation".
