Wähle eine der folgenden:

  • Iron

  • Magnesium

  • Sodium

Erklärung

Frage 3 von 12

1

Wähle von der Dropdown-Liste, um den Text zu vervollständigen.

Iron can be extracted from iron oxide using a process called ( oxidation, electrolysis, reduction ). This involves heating the ore with ( carbon, oxygen, copper ) monoxide to remove the oxygen from the compound. This process is also called a ( displacement, hydrolysis, combustion ) reaction, and gives two products: iron and ( carbon dioxide, carbon monoxide, copper ).
