Problem 87

Write the balanced chemical equations for (a) the complete combustion of acetic acid (CH3COOH), the main active ingredient in vinegar; (b) the decomposition of solid calcium hydroxide into solid calcium (II) oxide (lime) and water vapor; (c) the combination reaction between nickel metal and chlorine gas.

Step-by-Step Solution:

Answer : Combustion reaction of acetic acid : Step 1 When acetic acid undergoes combustion in air the products formed are carbon dioxide and water .the reaction given below is unbalanced reaction is CH3COOH(l)+O2CO2(g)+H2O(l). There are two atoms of C,4 atoms of H on the left ,only one carbon ,2 H on the right side of the equation.so we balance them by placing a 2 infront of CO2 and H2O CH3COOH(l)+O2(g) 2CO2(g) + 2H2O(l). This makes 6 O atoms on the right side but there are only 4 on the left side of the equation. Thus the balanced reaction is given as follows CH3COOH(l)+2O2(g) 2CO2(g) + 2H2O(l) Step 2 of 3 (b) When solid calcium hydroxide is heated, it decomposes into solid calcium (II) oxide and water vapor. The balanced equation for this reaction is:
