<p>To solve the question regarding the reaction of barium peroxide with phosphoric acid, we will follow these steps:</p><p><strong>Step 1: Write the Reactants</strong> Identify the reactants involved in the reaction. Here, we have: - Barium peroxide (BaO
hence, no reaction takes place in either of this case contrary to that of dilute sulphuric acid. In case of reaction of barium chloride with dilute hydrochloric acid, the double displacement reaction cannot take place due to same anions with both the reactants....
