Analyzing the gaseous outputs of industrial extraction setups provides insights into furnace efficie — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

The air blown into the furnace contains Nitrogen, which is inert and passes through. Coke burns to form $CO_2$, which reduces to $CO$. The resulting waste gas escaping the top of the blast furnace is roughly 60% Nitrogen, 30% $CO$, and 10% $CO_2$.
