Chemical equation
Required
Type of reaction
Solution
1. 3Ca + 2Fe(OH)3 → 2Fe + 3Ca(OH)2
Single replacement : one element replaces the other elements of a compound
2.2AlF3 + 3Na2O → Al2O3 + 6NaF
Double replacement : an ion exchange between two ion compounds in the reactant to form two new ion compounds
3.2Mg + O2 → 2MgO
Synthesis: 2 elements combine to form a single product
