Questions & Step-by-Step Solutions

What is the main purpose of using carbon in the extraction of metals from their ores?
  • Step 1: Understand what ores are. Ores are natural rocks that contain metals.
  • Step 2: Know that metals are often found in their combined form with other elements in ores.
  • Step 3: Learn that to get the pure metal, we need to separate it from these other elements.
  • Step 4: Recognize that carbon can help in this separation process.
  • Step 5: Identify that carbon acts as a reducing agent, which means it helps remove oxygen from the metal ore.
  • Step 6: Realize that when carbon is heated with the ore, it reacts with the oxygen, allowing the pure metal to be extracted.
  • Step 7: Remember that this process is commonly used for metals like iron in a method called smelting.
