Fe ----> Fe2+ + 2e-
A spectator ion is an ion that does not take part in the reaction. If you write out a normal equation. look for something that is the same on both sides and does not change state. This is a spectator ion and can be crossed out of the net ionic equation
This formula is FeCl2.
CHCl3
The formation of a salt is a chemical change. It is the result of the ionic bonding of a positive metal ion and a negative non-metal ion.
An ion
Ag+ + 2S2O32- --> [Ag(S2O3)3]-3
ion
No, it is not
FeI2
A spectator ion is an ion that does not take part in the reaction. If you write out a normal equation. look for something that is the same on both sides and does not change state. This is a spectator ion and can be crossed out of the net ionic equation
A "neutron ion" doesn't exist.
This formula is FeCl2.
2AgNO3 + FeCl22AgCl + Fe(NO3)2
The general word equation for salt formation by neutralization is acid + base.
The octet rule is the tendency to have eight electrons in the shell after ion or bond formation.. This gives the same configuration as a noble gas.
CHCl3
The chemical equation is:2 H2OH3O+ + OH-
