Question

What kind of chemical reaction does the chemical equation sodium + chlorine → sodium chloride represent?

A. Combustion
B. Decomposition
C. Single Replacement
D. Synthesis

Answer 1

D. Synthesis cause A + B --> AB Equation: 2Na + Cl2 --> 2NaCl

Answer 2

Answer: Option (D) is the correct answer.

Step-by-step explanation:

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

For example,
`Sodium + Chloride \rightarrow \text{Sodium chloride}`, is a synthesis reaction.

Decomposition reaction is a reaction in which a reactant or substance breaks into two or more substances.

For example,
`\text{Sodium chloride} \rightarrow Sodium + Chloride`, is a decomposition reaction.

In a single replacement reaction, an element replaces one atom from a compound.

For example,
`Zn+ CuCl_(2) \rightarrow ZnCl_(2) + Cu`

Thus, we can conclude that the chemical equation
`sodium + chlorine \rightarrow \text{sodium chloride}` represent synthesis reaction.
