Electron Transfer
Mixed ID Driving Forces
After HMK Check, find your assigned problem to share. Work together to solve if not complete yet.

2. 4) Transfer of electrons: Oxidation-Reduction
How to identify a redox reaction
Is there an atom that is an element on one side and in a compound on the other side? (often Single Replacement reactions)
Is there an element that has a different charge ion on both sides? (Many synthesis and decomposition reactions.)
Transfer of electrons is a driving force. Elements are driven to complete octets.
Note: All combustion reactions are driven by electron transfer.

3. Activity Series
For single replacement reactions, the determining factor is the place of the two metals in the activity series.
In general, a metal can displace any of the metals which are lower in the activity series:
Ex: Cu + AgNO3  Cu(NO3) Ag
Ex: Cu + Fe(NO3)3  Cu (NO3)2 + Fe
Ex: Zn + Fe(NO3)3  Zn (NO3)2 + Fe

4. Reactivity Series for Halogens
In general, a halogen can displace any of the halogens which are lower in the activity series for halogens.
Notice that the activity series of halogens is just their order within the periodic table.
Ex: F NaBr  2 NaF + Br2
Ex: Br NaCl  2 NaBr + Cl2

5. Practice ID driving forces
Balance, ID type, ID driving force
_____1. _____H3PO3  _____H3PO4 + _____PH3
_____2. _____Fe2O3 + _____C  _____CO + _____Fe
_____3. _____FeS + _____O2  _____Fe2O3 + _____SO2
_____4. _____NH3 + _____O2  _____NO + _____H2O
_____5 ._____Si + _____S8  _____Si2S4

6. More Practice ID driving forces
_____6. _____Hg2CO3  _____Hg + _____HgO + _____CO2
_____7. _____SiC + _____Cl2  _____SiCl4 + _____C
_____8. _____Al4C3 + _____H2O  _____CH4 + _____Al(OH)3
_____9. _____V2O5 + _____HCl  _____VOCl3 + _____H2O
_____10. _____Ag2S + _____KCN  _____KAg(CN)2 + _____K2S

7. Exit Slip - Homework Exit Slip: :
When the sulfuric acid in acid rain reacts with the calcium carbonate of marble statues, the reaction transforms the marble into calcium sulfate which crumbles away and also produces some water and carbon dioxide.
1) Convert to an equation including state descriptors. 2) Balance ) Identify the type classification. 4) Identify any driving forces.
What’s Due? (Pending assignments to complete.)
