1.	What are the different types of chemical reactions? Give one example for each with equation.
Answer» Chemical reactions can be classified in following types:\tCombination Reaction\tExample:\xa0When magnesium is burnt in air (oxygen), magnesium oxide is formed. In this reaction, magnesium is combined with oxygen.\tMg + O2 → 2MgO\t\tDecomposition Reaction\tExample:\xa0When calcium carbonate is heated, it decomposes into calcium oxide and carbon dioxide\tCaCO3 → CaO + CO2\t\tDisplacement Reaction\tExample:\xa0When zinc reacts with hydrochloric acid, it gives hydrogen gas and zinc chloride.Zn + 2HCl → ZnCl2\xa0+ H2\t\tDouble Displacement Reaction\tExample:\xa0When solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride.\tBaCl2\xa0+ Na2SO4\xa0\xa0→ BaSO4\xa0+ 2NaCl\t\tOxidation and Reduction Reaction\tWhen sodium hydroxide reacts with hydrochloric acid, it gives sodium chloride and water.\tNaOH + HCl → NaCl + H2O\t
