Question

categorize wach reaction as single, double, synthetic.. etc.

2 Fe(III) + 3 CuSO4 --> 3 Cu(II) + Fe2(SO4)3


Pb(NO3)2 + 2KI----> PbI2 + 2KNO3

Mg + 2 HCl---> MgCl2 + H2

2 H2O ----> 2 H2 + O2

2 Mg + O2 --> 2 MgO

Answer 1

1. single replacement
2. single replacement (technically, because KNO3 is soluble, there is not reaction)
3. single replacement
4. decomposition
5. synthesis

Answer 2

thank you
