`K_2 C_6 O_6` is called .

Options

A. Postassium per carbonte
B. Postassium permono carbonte
C. Potassium perdicarbonate
D. Potassiuym subacarbnonate

Answer

To determine the name of the compound \( K_2C_6O_6 \), we can follow these steps:

### Step 1: Analyze the Formula
The formula \( K_2C_6O_6 \) indicates that there are two potassium (K) atoms, six carbon (C) atoms, and six oxygen (O) atoms in the compound.

### Step 2: Simplify the Formula
We can simplify the formula by recognizing that \( K_2C_6O_6 \) can be expressed in terms of dicarbonate. The presence of six oxygen atoms suggests that we might be dealing with a compound related to carbonate or dicarbonate ions.

### Step 3: Identify the Ion
From the formula, we can see that there are two potassium ions (K\(^+\)), which typically pair with an anion. The structure \( C_6O_6 \) can be interpreted as containing two dicarbonate units, leading us to consider the possibility of it being a percarbonate or a related compound.

### Step 4: Name the Compound
Given that \( K_2C_6O_6 \) can be derived from two dicarbonate ions, it is identified as potassium per dicarbonate. Therefore, the name of the compound \( K_2C_6O_6 \) is **potassium per dicarbonate**.

### Final Answer
The compound \( K_2C_6O_6 \) is called **potassium per dicarbonate**.
