2. Double replacement

3. Synthesis

Further explanation

Given

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
