  1. Activity Series of Elements 8-3

  2. Will cobalt react with sodium chloride? Co(s) + NaCl(aq)  ? • Co(s) + NaCl(aq) NR (no reaction) • just because a chemical equation can be written doesn’t mean that is will actually happen!

  3. Activity Series • list of elements organized according to the ease with which the elements undergo certain chemical reactions* • most active metals (easiest to lose e-) are at the TOP and can replace a metal in a cmpd found below it in single displacement reactions • *metals: lose e- non-metals: gain e-

  4. Will the following react? IF so, write an equation. • Mn + H2O • Cd + O2  • Ag + HCl  300C

  5. Mn + H2O --30C NR needs steam • 2Cd + O2  2CdO anything above Ag reacts with oxygen and Cd is above • Ag + HCl NR any metal above H2 reacts and Ag is below

  6. Br2 + HCl  NR Br is below Cl • Cl2 + 2KI  2KCl + I2 Cl is above I2

  7. Section review/Practice Problems • Page 267 a-e • Page 271 # 34, 35, 36

  8. Section Review, p.267 • a. no • b. Br2 + 2KI  2KBr + I2 • c. no • d. Cd + 2HCl  CdCl2 + H2 • e. Mg + Co(NO3)2  Mg(NO3)2 + Co
