Explanation / Answer
1) type - double displacement
Iron(III) hydroxide will be the insoluble product.
This is a precipitation reaction
chemical equation:----FeCl3(aq) + 3NaOH(aq) --> Fe(OH)3(s) + 3NaCl(aq)
Complete ionic equation - Fe +3 + 3Cl -1 + 3Na +1 + 3OH -1 = 3Na +1 + 3 Cl -1 + FeOH3
A Net Ionic equation is the same thing as the complete ionic except that all of the common ions between the reactant and product sides have been canceled out. In this case, the only common ions are the Cl -1 and the Na +1. Cross these out on both sides to give the net ionic equation:
Fe +3 + 3OH -1 = FeOH3 --- net ionic equation -
2) type - decomposition
chemical - CuSO4
