answered-by-expert Expert Answer
In decomposition reaction single substance decomposes  to form two or more substances.
 
CaCO subscript 3 space space rightwards arrow with increment on top space CaO space plus CO subscript 2
In  combination  reaction two  or more  substances combine to form product.
C a O space plus C O subscript 2 rightwards arrow C a C O subscript 3 plus e n e r g y
Therefore it  is clear that two reactions are  opposite  to each other.
