Question

What type of chemical reactions are represented by the following equations? (i) A + B → C (ii) A + BC → AC + B (iii) A → B + C (iv) AB + CD → AD + BC

September 7, 2024

Answer

The types of chemical reactions represented by the given equations are:

A + B → C

Type: Combination (Synthesis) Reaction
Explanation: Two reactants (A and B) combine to form a single product (C).

A + BC → AC + B

Type: Single Displacement (Single Replacement) Reaction
Explanation: Element A replaces element B in the compound BC, forming AC and releasing B.

A → B + C

Type: Decomposition Reaction
Explanation: A single compound (A) breaks down into two or more simpler substances (B and C).

AB + CD → AD + BC

Type: Double Displacement (Double Replacement) Reaction
Explanation: The ions in two compounds exchange partners, forming two new compounds (AD and BC).

Here is a table summarizing the types of chemical reactions:

Reaction Equation	Reaction Type
A + B → C	Combination (Synthesis) Reaction
A + BC → AC + B	Single Displacement (Replacement) Reaction
A → B + C	Decomposition Reaction
AB + CD → AD + BC	Double Displacement (Replacement) Reaction
