2) decomposition reaction
3) neutralisation reaction

1)- For example barium metal and fluorine gas will combine in a highly exothermic reaction to form the salt barium fluoride: Another example is given by magnesium oxide combining with carbon dioxide: Often, reaction can fall into more than one category.

2)- A decomposition reaction occurs when one reactant breaks down into two or more products. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

3)- Using neutralisation

Farmers use lime (calcium oxide) to neutralise acid soils. Your stomach contains hydrochloric acid, and too much of this causes indigestion. Antacid tablets contain bases such as magnesium hydroxide and magnesium carbonate to neutralise the extra acid. Bee stings are acidic.

Answer 2

Answer:

Combination reaction:Mg+O2->MgO

Decomposition reaction:CaCO3->CaO+CO2

Neutralisation reaction->NaOH+HCl->NaCl+H2O
