Though coke is made from coal, it is used for metallurgical processes instead of coal. Give reason.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Composition of Coke and Coal:**
- Coke is derived from coal through a process called carbonization, where coal is heated in the absence of air. This process removes volatile substances and leaves behind a solid residue known as coke.
- Coal, on the other hand, contains a mixture of various substances, including carbon, hydrogen, sulfur, oxygen, and nitrogen.

2. **Coke's Purity and Carbon Content:**
- The resulting coke is primarily composed of carbon, with about 98% carbon content. This high purity makes it an excellent reducing agent in metallurgical processes.
