This is a neutralisation reaction as lead oxide is a base and nitric acid is an acid, which produces lead nitrate salt and water.2. Mg + 2HCl →MgCl2 + H2. This is a simple displacement reaction as hydrogen is displaced from chlorine from the hydrochloric acid.3. 2Fe + 3Cl2 →2FeCl3 . This is a combination reaction as iron and chlorine combines to form Iron (III) chloride.4. NaOH + HNO3 →NaNO3 + H2O. This is a titration raction, as sodium hydroxide solution and nitric acid is titrated to neutralise it.5. ZnSO4 + Na2CO3 →ZnCO3 + Na2SO4. This is a precipitation reaction, as it undergoes double displacement as precipitates Zinc carbonate. Regards, 1 View Full Answer Garvit Yadav answered this 3 is simple displacement reaction. 1
