Question

What type of reaction does this model represent?

1. single replacement
2. double replacement
3. Decomposition
4. double displacement

Answer 1

1. single replacement

Step-by-step explanation:

Single replacement can be represented by AB+C ⇄B+AC, which matches the picture

Double replacement and double displacement are the same kind of reaction and can be represented by AB+CD ⇄BD+AC

Decomposition reaction can be represented by AB ⇄A+B
