- Extracting Metals from their ores
- Heat it with carbon
- ZnO + C -> Zn + CO
- Metal ore is reduced and the carbon is oxidised.
- Issues
- Not pure enough, not worth mining
- Energy Costs
- Environmental Issues
- Pollution
- Calculate relative formula mass
- Iron Oxide Fe2O3
- Fe=56 O=16
- (56x2) + (16x3)
- 112 + 48
- =160
- 112 + 48
- Iron Oxide Fe2O3
- Relative mass of metal / Relative mass of ore x Amount of ore
- Metallic Bonding
- Strong but flexible - Malleable (can be bent into shape)
- Conducts electricity
- Lattic of positive ions
- Untitled
- Heat it with carbon
