Combustion, neutralisation and displacement template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
GCSE / IGCSE and NCERT Class 10 reaction types with word, balanced and ionic equations and observations: combustion of methane and magnesium, neutralisation of HCl by NaOH and of H₂SO₄ by CuO, and displacement of copper by zinc and of bromine by chlorine.
What the template shows
- Each reaction three ways: word equation, balanced symbol equation with state symbols, and ionic equation
- Combustion: fuel + oxygen → oxides; exothermic
- Methane (complete)
- methane + oxygen → carbon dioxide + water
- ΔcH = −890 kJ mol⁻¹; limited air: 2CH₄ + 3O₂ → 2CO + 4H₂O
- none: no ions in solution
- blue flame; CO₂ turns limewater milky
- magnesium + oxygen → magnesium oxide
- none (solid product); as half-equations Mg → Mg²⁺ + 2e⁻ and O₂ + 4e⁻ → 2O²⁻
- brilliant white flame, white powder
- Neutralisation: acid + base → salt + water
- Acid + alkali
- hydrochloric acid + sodium hydroxide → sodium chloride + water
- HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
- Na⁺ and Cl⁻ are spectators · ΔH ≈ −57 kJ mol⁻¹ (strong acid + strong base)
- temperature rises; indicator changes colour
- Acid + insoluble base
- sulfuric acid + copper(II) oxide → copper(II) sulfate + water
- H₂SO₄(aq) + CuO(s) → CuSO₄(aq) + H₂O(l)
- black solid dissolves; blue solution
- Displacement: a more reactive element pushes a less reactive one out of its compound (redox)
- Metal displacement
- zinc + copper(II) sulfate → zinc sulfate + copper
- Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s)
Drawn with 7 shapes – every one editable in MolDraw.

Frequently asked questions
Is the Combustion, neutralisation and displacement template free?
You can preview the Combustion, neutralisation and displacement template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates.
Can I edit the Combustion, neutralisation and displacement template?
Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.
Is the chemistry checked?
Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.
Which MO diagrams are included?
H₂ and He₂, N₂ and O₂ (showing s–p mixing and paramagnetic O₂), and carbon monoxide.
