Topic 4 – Extracting Metals & Equilibria

Reactivity Series

Metals are arranged by reactivity; more reactive metals displace less reactive metals

Displacement Reactions

A more reactive metal displaces a less reactive metal from its compound

Separating Metals from Oxides

Metals less reactive than carbon are reduced by heating with carbon; more reactive metals require electrolysis

Redox Reactions

Redox reactions involve both oxidation and reduction

Sustainable Development

Sustainable development meets present needs without compromising future generations

Reuse & Recycling

Materials can be reused or recycled to conserve resources and reduce waste

Life Cycle Assessments

Life cycle assessments evaluate environmental impact from raw materials to disposal

Reversible Reactions

Reversible reactions can proceed in both directions under different conditions

Dynamic Equilibrium

In a closed system at equilibrium the forward and reverse reactions occur at equal rates

Le Chatelier's Principle

If a system at equilibrium is disturbed
