2CH3COOH+ xCa→ Ca (CH3COO)2 +H2.Calculate value of "x".
Correct answer: A. 1
- A. 1
- B. 3
- C. 2
- D. 4
Explanation
Calcium is a Group 2 metal and forms a Ca2+ ion. To balance the charge of two acetate ions (CH3COO-), one calcium ion is needed. Therefore, the stoichiometric coefficient "x" for calcium metal is 1.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
