Galena (lead sulfide- PbS) is identified by its metallic luster, light to dark gray color, and high average density of 7.4.
The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.
Galena is primarily used as a lead ore, contributing to lead production. It is also used in the production of batteries, ammunition, and radiation shielding due to its high density. Additionally, galena is sometimes used in crystal healing and as a semiprecious stone in jewelry.
C. Hardness. Galena has a low hardness level, which causes it to break into tiny pieces rather than deform.
Galena is listed at 2.5 on the Mohs scale of mineral hardness.
Galena is in the sulfide group of minerals.
You can tell the difference in density between quartz and galena by measuring their mass and volume. Calculate the density by dividing the mass by the volume. Galena has a higher density than quartz, so the sample with higher density is likely to be galena.
The density of galena is between 7,2 and 7,6 g/cm3.
No, galena does not float in water because it has a higher density than water. This means that galena will sink when placed in water.
the specific gravity of galena is 7.4-7.6, so the average is 7.5
The density of galena is between 7,2 and 7,6 g/cm3.
The volume of a sample of galena with a mass of 300 g would depend on its density. The density of galena is approximately 7.5 g/cm^3. Using the formula Volume = Mass/Density, the volume can be calculated as 300 g / 7.5 g/cm^3 = 40 cm^3.
No, galena does not float on water because it has a high density of around 7.5 g/cm^3, which is heavier than water. Therefore, it will sink in water.
Minerals that have a density of around 2.1 include dolomite, pyrite, and galena. These minerals can vary slightly in density based on their specific composition and structure.
The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.
