Topic 3- Lecture 13 Flashcards
1
Q
Hydrogen displacement reaction
A
Hydrogen atoms in H2O are reduced as they gain electrons to form hydrogen gas
2 H2O + 2e- —–> H2 + 2OH-
2
Q
Element in one oxidation state simultaneously undergoes both oxidation and reduction
2Cu+ —–> Cu + Cu2+
A
Disproportionation Reaction 1
3
Q
Produces intermediate oxidation state
A
Disproportionation Reaction 2
Fe + 2Fe3+ ——> 3Fe2+
4
Q
Combustion Reactions
Organic compounds
A
Organic hydrocarbon —–> CO2 and H2O
No charges in net equation
5
Q
Combustion reactions
Elements
A
Presence of O produces oxide
S + O2 ——> SO2
6
Q
Donate protons in aqueous solutions
A
Acids
HCl —–> H+ + Cl-
7
Q
Halogen displacement reaction
A
Halogens bonded to themselves can take electrons from any halide ions below it in the family
Cl2 + 2Br —-> 2 Cl- + Br2
