Explanation:
2Al(s) + Fe₂O₃(s) ⟶ Al₂O₃(s) + 2Fe(s); ΔᵣH = ?
The formula for calculating the enthalpy change of a reaction by using the enthalpies of formation of reactants and products is
2Al(s) + Fe₂O₃(s) ⟶ Al₂O₃(s) + 2Fe(s)
ΔfH°/kJ·mol⁻¹: 0 -824.3 -1675.7 0
- Acids and bases both react with water and a lot of acids and bases are soluble in nature.
- Both acids and bases are electrolytes which means that they’re good conductors of electricity.
- Acids and bases both produce ions in water solution.
- Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH–).
