Question

Examine the equation.

Answer 1

the answer is synthesis

Answer 2

Answer: 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, $2Ca + O_{2} \rightarrow 2CaO$

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, $Zn + CuCl_{2} \rightarrow ZnCl_{2} + Cu$

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

For example, $Na_{2}S + 2HCl \rightarrow 2NaCl + HCl$

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