Catalytic converters are used in motor vehicles.They catalyse the conversion of potentially harmful gases produced in the combustion of motor fuel, into less harmful gases.The reactants for such a convers...

Zn_(s) + 2HCl_(aq) => ZnCl_2(aq)+ H_2(g)Evervessence, Zinc becomes smaller and then disappearsCut zinc in to smaller pieces to increase the surface area

The anode is the positive electrode so attracts negative ions. At the anode, negative ions lose electrons (they are oxidised).The resulting product depends on the ionic substance but is non-metal and is o...
