Consider the chemical reactions below to produce bis-acetylene (C4H2) from ruthenium (Ru) and acetylene (C2H2).
I. C2H2 + Ru → RuC2H2
II. RuC2H2 + C2H2 → Ru(C2H2)2
III. Ru(C2H2)2 → RuH2 + C4H2
Respectively, reactions I, II, and III are classified as:
A.Synthesis, Double Displacement, Synthesis
B.Synthesis, Synthesis, Decomposition
C.Synthesis, Combination, Double Displacement
D.Double Displacement, Double Displacement, Single Displacement
