Topic 3- Lecture 13 Flashcards
Hydrogen displacement reaction
Hydrogen atoms in H2O are reduced as they gain electrons to form hydrogen gas
2 H2O + 2e- —–> H2 + 2OH-
Element in one oxidation state simultaneously undergoes both oxidation and reduction
2Cu+ —–> Cu + Cu2+
Disproportionation Reaction 1
Produces intermediate oxidation state
Disproportionation Reaction 2
Fe + 2Fe3+ ——> 3Fe2+
Combustion Reactions
Organic compounds
Organic hydrocarbon —–> CO2 and H2O
No charges in net equation
Combustion reactions
Elements
Presence of O produces oxide
S + O2 ——> SO2
Donate protons in aqueous solutions
Acids
HCl —–> H+ + Cl-
Halogen displacement reaction
Halogens bonded to themselves can take electrons from any halide ions below it in the family
Cl2 + 2Br —-> 2 Cl- + Br2
