Answer 1

The reactions are classified as synthesis, precipitation, single displacement, and decomposition reactions.

Step-by-step explanation:

a) Synthesis

b) Precipitation

c) Single Displacement

d) Decomposition

The balanced chemical equations corresponding to the given reactions are:

a) S + O → SO2

b) CaCl2 + 2AgNO3 → Ca(NO3)2 + 2AgCl

c) Zn + CuSO4 → Cu + ZnSO4

d) 2Na2O → 4Na + O2
