BLAST FURNACE 🔥 | COMBINED SCIENCE PAST PAPER 2020 Let’s work through a Combined Science past paper question on the Blast Furnace! 🔥⚙️ This is June 2020, Question 3, and in this video I explain both the chemistry behind the blast furnace and how to answer the questions. We cover: 📌 Identifying molten iron and slag 📌 The three raw materials: coke, haematite and limestone 📌 What happens near the top of the blast furnace 📌 How carbon monoxide reduces iron(III) oxide 📌 The reduction equation: 3CO + Fe₂O₃ → 2Fe + 3CO₂ 📌 How to approach the past-paper questions and get the required points The goal isn't just to memorise the answers — it's to understand what is happening inside the furnace and why. Another past paper question broken down. 🧪🔥 #BlastFurnace #IronExtraction #CombinedScience #Chemistry #ChemistryPastPapers #PastPaper #IGCChemistry #ChemistryRevision #IronExtraction #Reduction #Redox #Metallurgy #ScienceRevision #PastPaperQuestions#ScienceStudent #ChemistryStudent #LearnChemistry #STEM #GCSEScience #IGCSEScience #olevel#olevels#zimsec#zimtiktokers🇿🇼🇿🇼🇿🇼 #foryou #fyp
