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...

Atoms can be modelled as point positive charges with clouds of electrons around them. When two atoms come together close enough, a region of higher electron density forms between the two atoms. This means...

The outer shell of electrons in metals are delocalised, meaning they are able to travel freely around the metal.

The negative electrons hold the positively charged metal ions together. The poo...
