Answer 1

Answer:

XY → X + Y general reaction represents a decomposition reaction where a molecule is “broken” in two separate molecules

Explanation:

In a double-displacement reaction two molecules will exchange atoms or group of atoms, and it should look like this:

XY + AB →  XA + YB

In a combustion reaction molecules are reacting with oxygen generating oxides.  

XY + O$_{2}$ → XO + YO

In a single-displacement reaction an atom or a group of atoms in a molecule are replaced by other atoms, and it should look like this:

XY + A → XA + Y
