Explain various type of reaction with example |
| Answer» Various types of reaction are ------------------>. 1.COMBINATION REACTION- the reaction in which two or more substance combine together to form a new substance is known as combination reaction .C+O2--------->CO2. 2. DECOMPOSITION REACTION- the reaction in which one substance is broken into two or more simpler substance is known as decomposition reaction.CO2---> C+O2. 3.DISPLACEMENT REACTION- the reaction in which more reactive element displaces the less reactive element.Zn+CuSO4----> ZnSo4+Cu. 4. DOUBLE DISPLACEMENT-the reaction in which two ionic compounds are exchanged is known as double displacement reaction.AgNO3+NaCl--------->AgCl+NaNO3. 5.NEUTRALISATION REACTION- the reaction in which acids and bases react with each other forming salt and water.NaOH+HCl-->NaCl+H2O. 6. PRECIPITATION REACTION- the reaction in which one of the products formed are solid precipitates.Ca(OH)2+CO2--->CaCO3+H2O. 7.EXOTHERMIC REACTION- the reaction in which heat is given out .C+O2->CO2+heat. 8. ENDOTHERMIC REACTION- the reaction in which heat is absorbed.C+H2O+heat-->CO+H2 | |
