6. Acids and Metals Metal + Acid Salt + hydrogen Zinc +Sulphuric Acid Zinc Sulphate+ Hydrogen Neutralisation

7. Other acids and metals Metal + Acid NEUTRALISATION Exercise... Salt +Hydrogen e.g. Zinc + Hydrochloric AcidZinc Chloride + Hydrogen

8. About Corrosion... zinc + sulphuric acid zinc sulphate + hydrogen The metal was used up as the hydrogen was made. When metals are used up by chemical reactions we call it CORROSION.

9. Acids and Carbonates Acids react with carbonates to make Carbon Dioxide.
