In Goldschmidt's aluminothermite process, thermite mixture contains ______ parts of `Fe_(2)O_(3)` and one part of aluminium.

Explanation

To solve the question regarding the Goldschmidt aluminothermite process, we need to identify the proportions of the components in the thermite mixture.

### Step-by-Step Solution:

1. **Understand the Thermite Reaction**: The Goldschmidt aluminothermite process involves a reaction where aluminum is used to reduce metal oxides. In this case, we are focusing on iron(III) oxide (Fe₂O₃).

2. **Identify the Components**: The thermite mixture consists of iron(III) oxide (Fe₂O₃) and aluminum (Al).

3. **Determine the Proportions**: According to the process, the standard ratio used in the thermite mixture is 3 parts of Fe₂O₃ to 1 part of aluminum.

4. **Conclude the Answer**: Therefore, the answer to the question is that the thermite mixture contains **3 parts of Fe₂O₃** and **1 part of aluminum**.

### Final Answer:
In Goldschmidt's aluminothermite process, the thermite mixture contains **3 parts of Fe₂O₃** and **1 part of aluminum**.
