The 5 Types Of Reactions

The 5 Types of Reactions Ms. Komperda March 22 nd & 23 rd We classify reactions into 5 categories so that we may more easily predict the products.

The 5 Types of Reactions Double Replacement Decomposition Single Replacement Synthesis Combustion

Synthesis Reaction Synthesis reaction – 2 substances combine to form a single product A + B  AB +  2Mg(s) + O 2 (g)  2MgO(s) Magnesium and oxygen combine to form magnesium oxide. 2H 2 (g)+ O 2 (g)  2H 2 O(l) Hydrogen and oxygen combine to form dihydrogen monoxide

Decomposition Reaction ,[object Object],[object Object], + 2H 2 O 2 (aq)  O 2 (g)+ 2H 2 O(l) Hydrogen peroxide decomposes into oxygen gas and dihydrogen monoxide. 2NaCl(s)  2Na(s) + Cl 2 (g) Sodium chloride decomposes into sodium and chlorine gas.

Single Replacement Reaction ,[object Object],[object Object],+  + AgNO 3 (aq) + Cu(s)  Ag(s) + CuNO 3 (aq) Copper replaces silver in silver nitrate to copper (I) nitrate and silver. Zn(s) + 2HCl(aq)  H 2 (g) + ZnCl 2 (aq) Zinc replaces hydrogen in hydrogen chloride to yield hydrogen gas and zinc chloride.

Double Replacement Reaction ,[object Object],[object Object],+  + HCl(aq) + NaOH(aq)  HOH(l) + NaCl(aq) Hydroxide and chlorine switch places to hydrogen hydroxide (water) and sodium chloride Na 2 S(aq) + Zn(NO 3 ) 2 (aq)  2NaNO 3 (aq) + ZnS (s) Sulfur and nitrate switch places to form sodium nitrate and zinc sulfide.

Combustion Reaction ,[object Object],[object Object],CH 4 (g) + 2O 2 (g)  2H 2 O (l) + CO 2 (g) Methane burns in oxygen to produce water and carbon dioxide. C 12 H 22 O 11 (s) + 12O 2 (g)  11H 2 O(l) + 12CO 2 (g) Sucrose burns in oxygen to produce water and carbon dioxide.
