Which type of reaction does not fit the descriptive statement?
Select all that apply.
A. Double-displacement
B. Single-displacement
C. Synthesis
D. Decomposition
E. Combustion
C & D right?

Answer 1

I agree.
Synthesis is 2Na + O2 ==>2Na2O2
Decomposition is Na2CO3 ==> Na2O + CO2
Neither meets the criteria in the problem.

I'm glad at least DrBob is still around.
