A. Complete and balance the following reactions. Give the physical states of all the products. Name the type of each reactions. (i)HCl(aq)+Ca(OH)2(aq)--->? (ii)(NH4)2CO3(aq)+AgNO3(aq)--->? B. Calculate the oxidation number of each element in the reactants and products. Identify the oxidizing agent and reducing agent based on the change in the oxidation number. Explain your answer. 2H2O(aq)+ClO4-(aq)---> ClO2-(aq)+2H2O(l)+2O2(g)
