N a single-displacement reaction, one element displaces another element in a compound.
The general equation for a single-displacement reaction is:
A + B-C → A-C + B
A and B must be either different metals (including H) or different halogens.
Chemists have devised an Activity Series. It lists the metals and nonmetals in decreasing order of chemical activity. An element that is higher in the series will displace an element that is below it. This enables chemists to predict which combinations will undergo single displacement reactions.
The Heisenberg Uncertainty Principle states that it is impossible to determine simultaneously both the position and the velocity of a particle. The detection of an electron, for example, would be made by way of its interaction with photons of light.
The balanced half reactions are
4 Fe2+ ====> 4 Fe3+ + 4 e-
<span>MnO42- + 8 H+ + 4 e- ===> Mn2+ + 4 H2O
The net ionic equation is
4 Fe2+ + </span>MnO42- + 8 H+ ===> 4 Fe3+ + Mn2+ + 4 H2O<span />
Electronic configuration is given by
- 1s orbital is filled
- 2s orbital is unfilled
So
The answer is somewhat acidic
