I need help with the following problems: 1) When aqueous solutions of potassium carbonate and aluminum chloride are combined, solid aluminum carbonate and a solution of potassium chloride are formed. The net ionic equation for this reaction is: 2 )When aqueous solutions of sodium nitrite and hydrochloric acid are mixed, an aqueous solution of sodium chloride and nitrous acid results. Write the net ionic equation for the reaction. 3) Does a reaction occur when aqueous solutions of sodium carbonate and...
Reactants Observation(s) Type of Reaction Balanced Molecular Equation aqueous barium chloride + aqueous sodium sulfate A white solid forms after the solutions are mixed together. Precipitation Reaction BaCl(aq) + Na SO.(aq) - BaSO (s) + 2 NaCl(aq) zinc metal + hydrochloric acid Bubbles are observed after the solutions are mixed together. The zinc appears to be smaller in size. aqueous sodium phosphate + aqueous copper(II) sulfate A solid forms after the solutions are mixed together. copper metal + aqueous silver...
