The 6 Types of Chemical Reactions 1.) Synthesis – Starts with two elements which combine to form a product. Ex. – C (s) Ex. – H2 + O2 (s) Ex. – 2Sb (g) + Cl2 CO2 (g) (g) 2HCl (g) + 3Br2 (s) A + B AB 2SbBr3 (l) (s) 2.) Decomposition – Starts with one compound which breaks into two products. AB A + B Ex. – 2Ag2O (s) 4Ag Ex. – 2HgO Ex. – 2NO (s) 2Hg + O2 (s) + O2 (s) N2 (g) + O2 (g) (g) (g) (g) 3.) Single Replacement – Starts with one element and one compound and the metals switch with metals or the non-metals switch with non-metals. Ex. – 3CuCl2 Ex. – Cl2 (g) + 2Fe (s) 2FeCl3 (aq) (s) + 3Cu + 2KI (aq) 2KCl (aq) + I2 Ex. – 2AgNO3 (aq) A + BX B + AX or Y + BX X + BY (aq) (g) + Cu (s) Cu(NO3)2 (aq) + 2Ag (s) 4.) Double Replacement – Starts with two compounds and the metals switch places. AX + BY AY + BX Ex. – AgNO3 Ex. – 2NaCl (aq) (aq) + NaCl + H2SO4 Ex. – Ba(NO3)2 (aq) NaNO3 (aq) (aq) (aq) Na2SO4 + Na2SO4 (aq) + AgCl (aq) BaSO4 (aq) + 2HCl (aq) (aq) + 2NaNO3 (aq) 5.) Neutralization – A double replacement that involves an acid and a base. Acids start with H and bases with OH. Ex. – HCl HX + YOH YX + HOH (water) (aq) Ex. – H2SO4 + NaOH (aq) NaCl (aq) + 2KOH (aq) Ex. – H3PO4 (aq) + Ba(OH)2 (aq) + HOH K2SO4 (aq) (aq) (l) + 2HOH Ba3(PO4)2 (aq) (l) + 2HOH (l) 6.) Combustion – Starts with carbon and Hydrogen compound and oxygen (burning). CxHy + O2 CO2 + H2O Ex. – C5H12 (l) Ex. – C5H12O2 + 8O2 (s) (g) + 7O2 5CO2 (g) (g) 5CO2 + 6H2O (g) (g) + 6H2O (g) 1
