1) ___Mg + ___Fe203 → ___Fe + MgO
Type of reaction: __________

2. ___C2H4 + ___O2 → ___CO2 + ___H20
Type of reaction:_____________

3. ___PbSO4 → ___PbSO3 + ___O2
Type of reaction:___________

Answer 1

___ represents a space that must be filled in

Answer 2

The 5 types of chemical reactions are:
1. Synthesis
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion

Answer 3

the first reaction is a single replacement reaction and is also a oxidization-reduction reaction.
the second reaction is a combustion reaction.
the third reaction is a decomposition reaction because a single compound is splitting up into multiple compounds.

Answer 4
