The compounds having the general molecular formula `A^(2+)Fe_(2.04)` are called ……….. .

Answer

To solve the question regarding the compounds with the general molecular formula \( A^{2+}Fe_{2.04} \), we can follow these steps:

### Step 1: Analyze the Given Molecular Formula
The formula given is \( A^{2+}Fe_{2.04} \). Here, \( A \) is a cation with a \( 2+ \) charge, and \( Fe \) represents iron.

### Step 2: Identify the Nature of \( A \)
Since \( A \) has a \( 2+ \) charge, it indicates that \( A \) is a metal. Metals tend to lose electrons and form positive ions. Therefore, we can conclude that \( A \) is a metallic element.

### Step 3: Understand the Composition of the Compound
The formula indicates that there are 2.04 iron atoms associated with the metal \( A \). This suggests that the compound is a type of alloy or a mixed metal compound.

### Step 4: Determine the Type of Compound
Compounds that contain iron and another metal in such a configuration are commonly known as ferrites. Ferrites are typically magnetic materials composed of iron oxides combined with other metals.

### Step 5: Conclude the Type of Compound
Based on the analysis, the compounds having the general molecular formula \( A^{2+}Fe_{2.04} \) are classified as ferrite compounds.

### Final Answer
The compounds having the general molecular formula \( A^{2+}Fe_{2.04} \) are called **ferrite compounds**.
