Several properties for zinc (Zn) are listed below:
• brittle at room temperature, but malleable between 100°C and 150°C • bluish-white in color
• burns in air at high temperatures, giving off zinc oxide (ZnO) gas
• conducts heat and electricity
• sinks in water
• reacts with acids and bases
• exposed surfaces tarnish in moist air
a. Identify two physical properties of zinc from the list. Explain why the properties you identified are physical properties and not chemical properties.
b. Identify two chemical properties of zinc from the list. Explain why the properties you identified are chemical properties and not physical properties.
