Copper and iron are metals with many useful applications.
Both metals:
Choose two properties from the list that make copper a suitable metal for electromagnets.
Choose two properties from the list that make iron a suitable metal for heavy-duty cooking pans.
Titanium and steel are also compared for specialized engineering tasks. Consider these three differences:
Using this information: Suggest why titanium is a better metal than steel for building reaction vessels in chemical processing plants.
Suggest why steel is a better metal than titanium for making high-use railway tracks.
The reaction between magnesium powder and iron(III) oxide is highly energetic and can be shown by the chemical equation:
3Mg+Fe2O3→3MgO+2Fe 3\text{Mg} + \text{Fe}_2\text{O}_3 \rightarrow 3\text{MgO} + 2\text{Fe} 3Mg+Fe2O3→3MgO+2FeState what is meant by the term exothermic.
Use the reaction equation to compare the reactivity of magnesium and iron, explaining your reasoning.
Identify which element is oxidised in this reaction and give a reason for your choice.
During the reaction, pure iron is produced as a molten liquid. Explain why the iron is produced in a molten state.
