Name an oxide and carbonate containing oxygen.

To solve this question, we need to identify compounds that contain oxygen in both oxide and carbonate categories.

### Oxide

An **oxide** is a compound that contains at least one oxygen atom combined with another element. A common example of an oxide is **water** (\(H_2O\)), but since water is not typically considered a standard oxide for this type of question, a more common example is **carbon dioxide** (\(CO_2\)) or **iron(III) oxide** (\(Fe_2O_3\)).

**Example**:
- **Iron(III) oxide**: This compound consists of iron (Fe) and oxygen (O) and has the formula \(Fe_2O_3\).

### Carbonate

A **carbonate** is a compound that contains the carbonate ion, \(CO_3^{2-}\), along with another element. A well-known example of a carbonate is **calcium carbonate** (\(CaCO_3\)), which is commonly found in limestone and marble.

**Example**:
- **Calcium carbonate**: This compound consists of calcium (Ca), carbon (C), and oxygen (O) and has the formula \(CaCO_3\).

### Summary

- **Oxide**: Iron(III) oxide (\(Fe_2O_3\))
- **Carbonate**: Calcium carbonate (\(CaCO_3\))

Both compounds contain oxygen and exemplify the characteristics of oxides and carbonates.
