In a metallurgic industry, iron metal is produced by heating the mixture of hematite ore, Fe2O3
with carbon. If 0.8 tons of this iron ore is used, find out:
the mass in tones of the reacted carbon.
b. the mass in kilograms of the obtained iron.
the volume of the obtained gas at STP.
(Fe=56, C-12, O=16, at STP: 44g of CO2 has 22.4L)
