Answer» Types of chemical reaction are. 1. Combination reaction- in which two or more substance combine together to form a new substance.C+O2-CO2. 2. Decomposition reaction- in which a substance is broken into two or more subatances.CO2-C+O2. 3. Displacement reaction- in which more reactive element displaces less reactive element.CuSO4+Zn-ZnSO4+Cu. 4. Double displacement reaction- in which ionic compounds are exchanged.AgNO3+NaCl-AgCl+ NaNO3. 5. Precipitation reaction - in which precipitates are formed.Ca(OH)2+CO2-CaCO3 +H2O. 6. Neutralisation reaction - reaction between an acid and base forming salt and water .NaOH+HCl- NaCl+H2O. 7. Exothermic reaction- in which heat is given out.C+O2-CO2+heat. 8. Endothermic reaction- in which heat is absorbed.C+H2O+heat-CO+H2. Five types of chemical reactions are there 1 combination2 decomposition 3 displacement4 double displacement 5 oxidation and reduction |
