 Development of TargetES-E3.5 |
|
| ES-E3.5 | Describe what happens when metals react with oxygen, water and acids |
| Describe the reactions of different metals with oxygen, water and dilute acid. | |
| State that these reactions give an indication of the reactivity of the metal. | |
| Use idea of reactivity series to explain displacement reactions. | |
| Relate the reactivity of metals to their uses to include aluminium, zinc, iron (steel), lead, copper, silver and gold. | |
| Explain why some metals are found uncombined in the earth while most are found as compounds (ores). | |
| State that corrosion is a chemical reaction which involves the surface of a metal changing from an element to a compound. | |
| State some ways to slow down or prevent corrosion. | |
