Question

Most chemical reactions can be classified as one of these six basic reaction types: Synthesis (combination) Decomposition Single Replacement (oxidation-reduction) Double Replacement (precipitation) Acid-Base (neutralization) Combustion Write balanced equations for each of the following examples: Synthesis Reaction: A + B rightarrow AB Sodium (s) + chlorine (g) rightarrow sodium chloride (s) Decomposition Reaction: AB rightarrow A + B sodium bicarbonate (s) rightarrow carbon dioxide (g) + sodium carbonate (s) + water (l) Single Replacement Reactions: AB + C rightarrow A + CB hydrochloric acid, HCl (aq) + magnesium (s) rightarrow magnesium chloride (aq) + hydrogen (g) Double Replacement Reactions: AB + CD rightarrow_AD + CB calcium chloride (aq) + ammonium hydroxide (aq) rightarrow calcium hydroxide (s) + ammonium chloride Acid-Base Reactions: HA + BOH rightarrow BA + H_2O Sulfuric Acid, H_2SO_4 (aq) + potassium hydroxide (aq) rightarrow potassium sulfate (aq) + water (l) Combustion Reactions: Fuel + O_2(g) rightarrow CO_2(g) + H_2O(g) Hexane, C_6H_14 (l) + oxygen (g) rightarrow carbon dioxide (g) + water (g)

Explanation / Answer

Balanced equations for the requested reactions:

1)

2 Na + Cl 2 2 NaCl

2)

NaHCO3 Na2CO3 + H2O + CO

3)

Mg (s) + 2 HCl (aq) --> MgCl 2 (aq) + H 2 (g)

4)

2NH4Cl + Ca(OH)2 = CaCl2 + 2NH3 (g) + 2H2O

5)

H2SO4 + KOH = K2SO4 + H2O

6)

2C6H14(hexane) + 13O2 (oxygen) ----> 6CO2 + 14H2O
