Problem 1.20

(a) Read the following description of the element zinc and indicate which are physical properties and which are chemical properties.

Zinc melts at $$420^{\circ} \mathrm{C}$$. When zinc granules are added to dilute sulfuric acid, hydrogen is given off and the metal dissolves. Zinc has a hardness on the Mohs scale of 2.5 and a density of $$7.13 \mathrm{~g} / \mathrm{cm}^{3}$$ at $$25^{\circ} \mathrm{C}$$. It reacts slowly with oxygen gas at elevated temperatures to form zinc oxide, ZnO.

(b) Which properties of zinc can you describe from the photo? Are these physical or chemical properties?

Step-by-Step Solution:

Step 1 of 5) (a) Read the following description of the element zinc and indicate which are physical properties and which are chemical properties. (b) Which properties of zinc can you describe from the photo Are these physical or chemical properties The SI base unit of mass is the kilogram (kg), which is equal to about 2.2 pounds (lb). This base unit is unusual because it uses a prefix, kilo-, instead of the word gram alone. We obtain other units for mass by adding prefixes to the word gram. Temperature, a measure of the hotness or coldness of an object, is a physical property that determines the direction of heat flow. Heat always flows spontaneously from a substance at higher temperature to one at lower temperature. Thus, the influx of heat we feel when we touch a hot object tells us that the object is at a higher temperature than our hand. The temperature scales commonly employed in science are the Celsius and Kelvin scales. The Celsius scale was originally based on the assignment of 0 °C to the freezing point of water and 100 °C to its boiling point at sea level (Figure 1.19).
