Examine the equation. 2ca + o2 → 2cao what is the best classification for the equation's reaction? single displacement decomposition synthesis double displacement

the answer is synthesis

Option (c) is the correct answer.

Explanation:

A synthesis reaction is defined as a reaction in which two substances or atoms combine together to result in the formation of a compound.

For example,

Here, calcium and oxygen combine together to form compound calcium oxide.

Whereas in a decomposition reaction, a compound decomposes into two atoms.

A single displacement reaction is a reaction in which one element is displaced by another element.

For example,

A double displacement reaction is a reaction in which elements of two compounds interchange with each other forming two new compounds.

For example,

Hence, we can conclude that given reaction is a synthesis reaction.
