(a) Read the following description of the element zinc andindicate which are physical properties and which are chemicalproperties.Zinc melts at 420 °C. When zinc granules are added to dilutesulfuric acid, hydrogen is given off and the metal dissolves.Zinc has a hardness on the Mohs scale of 2.5 and a density of7.13 g>cm3 at 25 °C. It reacts slowly with oxygen gas at elevatedtemperatures to form zinc oxide, ZnO.
