Final answer:
(B) K₂C₂O₄ + Ba(OH)₂ → 2KOH + BaC₂O₄
The correct balanced molecular equation for the reaction between potassium oxalate and barium hydroxide is K₂C₂O₄ + Ba(OH)₂ → 2KOH + BaC₂O₄.
Step-by-step explanation:
The balance of the chemical equation we are discussing involves the reaction between potassium oxalate (K₂C₂O₄) and barium hydroxide (Ba(OH)2). When balancing this reaction, you have to ensure that there are equal numbers of each type of atom on both sides of the equation. After analyzing the options, the correct balanced molecular equation for the reaction is:
K₂C₂O₄ + Ba(OH)₂ → 2KOH + BaC₂O₄
In this balanced equation, one molecule of potassium oxalate reacts with one molecule of barium hydroxide to form two molecules of potassium hydroxide and one molecule of barium oxalate, while conserving mass and the number of atoms of each element.
