Answer

Brief Explanations:

  1. A single - displacement reaction has the general form where one element replaces another in a compound. In the reaction $A + BC\rightarrow AC + B$, element $A$ displaces element $B$ from the compound $BC$.
  2. The reaction $A + B\rightarrow AB$ is a synthesis reaction where two or more substances combine to form a single compound.

Answer:

  1. C. $A + BC\rightarrow AC + B$
  2. C. Synthesis
