The layers on the rocks are because of different deposition of sediments. Different sediments deposited over the rocks through wind, water and ice over the ages.
Hence, the correct answer is D.
Answer:
The percentage of germanium in germatite is 6.0003%.
Explanation:
Mass of an ore of germanite = 1.00 grams
Mass of germanium chloride = 0.177 grams
Percentage of germanium in germanium chloride = 33.9%
Let the mass of germanium present in germanium chloride be x.
Percentage of an element in a compound:
x = 0.060003 grams
Percentage of germanium in an ore of germanite:
The percentage of germanium in germatite is 6.0003%.
