Question

types of chemical reactions
identify the type of chemical reaction (synthesis, decomposition, single displacement or replacement, double displacement or replacement).
1 ab + c → ac + b
2 ab + cd → ad + cb
3 ab → a + b
4 a + b → ab
5
6
7

Explanation:

Step1: Recall reaction - type definitions

Synthesis: A + B → AB; Decomposition: AB → A + B; Single - displacement: AB + C → AC + B; Double - displacement: AB+CD → AD + CB.

Step2: Analyze reaction 1

AB + C → AC + B follows the single - displacement pattern.

Step3: Analyze reaction 2

AB + CD → AD + CB follows the double - displacement pattern.

Step4: Analyze reaction 3

AB → A + B follows the decomposition pattern.

Step5: Analyze reaction 4

A + B → AB follows the synthesis pattern.

Step6: Analyze reaction 5

A compound breaks into two parts, so it's decomposition.

Step7: Analyze reaction 6

AB + CD → AD + CB (represented by colored balls), so it's double - displacement.

Step8: Analyze reaction 7

A + BC → AC + B, so it's single - displacement.

Answer:

1. Single displacement
2. Double displacement
3. Decomposition
4. Synthesis
5. Decomposition
6. Double displacement
7. Single displacement
