Match the minerals with the names of the oxides they consist of: MINERALS HEMATITE Fe2O3 QUARTZ SiO2 BAUXITE Al2O3 CASSITERITE SnO2 PYROLUSITE MnO2 NAMES OF OXIDES 1 Manganese oxide (IV) 2 Tin oxide (IV) 3 Aluminum oxide 4 Silicon oxide 5 Iron oxide (III)

Solution:

• HEMATITE Fe2O3 - 5 Iron oxide (III)
• QUARTZ SiO2 - 4 Silicon oxide
• BAUXITE Al2O3 - 3 Aluminum oxide
• CASSITERITE SnO2 - 2 Tin oxide (IV)
• PYROLUSITE MnO2 - 1 Manganese oxide (IV)

Final Answer: The correct matches are: Hematite - Iron oxide (III), Quartz - Silicon oxide, Bauxite - Aluminum oxide, Cassiterite - Tin oxide (IV), Pyrolusite - Manganese oxide (IV).
