Question

23 choose the type of reaction for each equation. a + b ⟶ ab is for – choose the correct answer – reactions. ab ⟶ a + b is for – choose the correct answer – reactions. ab + c ⟶ ac + b is for – choose the correct answer – reactions. clear all

Explanation:

1. For the reaction \( A + B

ightarrow AB \), two substances combine to form one new substance. This fits the definition of a synthesis reaction.

1. For the reaction \( AB

ightarrow A + B \), one substance breaks down into two or more substances. This is a decomposition reaction.

1. For the reaction \( AB + C

ightarrow AC + B \), an element (C) replaces another element (B) in a compound (AB). This is a single - replacement (or single - displacement) reaction.

Answer:

• \( A + B

ightarrow AB \) is for synthesis reactions.

• \( AB

ightarrow A + B \) is for decomposition reactions.

• \( AB + C

ightarrow AC + B \) is for single - replacement (single - displacement) reactions.
