Question

The following equation represents which of the following types of reaction?

2 Na(s) + Cl2(g) ---> 2 NaCl(s)

Select one:
a. Decomposition.
b. Double replacement.
c. Single replacement.
d. Synthesis.​

Answer 1

Answer:

Synthesis

Explanation:

Types of reactions and how they are typically written :

Synthesis : A + B ==> AB

Decomposition : AB ==> A + B

Double Replacement : AB + CD ==> AC + BD

Single Replacement : AB + C ==> AC + B

We have the following equation :

2 Na(s) + Cl2(g) ---> 2 NaCl(s)

This equation follows the A + B ==> AB structure as the two substances are being added together in the reactants side and are then together as the product.

So the equation following synthesis
