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[tex]_{2}[/tex] → 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
