Question

current attempt in progress
four major types of chemical reaction were studied in this chapter. select the type of reaction that is best represented by the following general forms of equation:

1. ab → a + b
2. ab + cd → ad + cb
3. a + b → ab
4. a + bc → b + ac (a is a metal, which is more reactive than the metal b)

etextbook and media

Explanation:

1. For \(AB

ightarrow A + B\), it is a decomposition reaction where a single compound breaks down into two or more simpler substances.

1. For \(AB+CD

ightarrow AD + CB\), it is a double - displacement reaction. In this reaction, the positive and negative ions of two ionic compounds exchange partners.

1. For \(A + B

ightarrow AB\), it is a combination (synthesis) reaction where two or more substances combine to form a single compound.

1. For \(A+BC

ightarrow B + AC\) (where \(A\) is a more reactive metal than \(B\)), it is a single - displacement reaction. A more reactive element displaces a less reactive element from its compound.

Answer:

1. Decomposition reaction
2. Double - displacement reaction
3. Combination (synthesis) reaction
4. Single - displacement reaction
