Question

the teacher provided the table below showing the different properties of a few minerals. students were instructed to use the table to identify the minerals numbered 1 - 6. beside the table is a list of deons observations for mineral #3. observations for mineral #3 color, transparent color of powder, left on porcelain plate, white. it can scratch all other mineral samples. density - 3.69 g/cm based on deons observations, use the table to interpret the data and identify mineral #3. quartz feldspar sulfur

Explanation:

Step1: Analyze color and streak

Mineral #3 has a transparent color and a white streak. In the table, Quartz has a transparent color and a white streak, Feldspar has a white color (not transparent) and a colorless streak, and Sulfur has a yellow color (not transparent) and a white streak. So based on color and streak, it could be Quartz or Sulfur.

Step2: Analyze hardness

Mineral #3 can scratch all other mineral samples. Hardness is related to scratching ability. The higher the hardness number, the more it can scratch other minerals. Corundum has the highest hardness of 9 in the table, but its density is 4.0 \(g/cm^{3}\). Quartz has a hardness of 7. Sulfur has a hardness of 2. Since it can scratch all others (except maybe Corundum, but density rules out Corundum as density of mineral #3 is 3.69 \(g/cm^{3}\) close to Quartz's 2.6 \(g/cm^{3}\) (there might be a measurement error in density, but other properties match better). Also, Sulfur's hardness is too low (2) to scratch most minerals in the table.

Answer:

Quartz
