Two students are debating the classification of graphite (chemical formula: C). With which student do you agree? Student 1: I think that graphite belongs in the "other" category. It has carbon, but it doesn't have oxygen, so according to the definition, it cannot be a carbonate. Student 2: But the word "carbonate" has the word "carbon" in it! I think that if any mineral has carbon in its chemical formula, it must be a carbonate. Both students 1 / 1 pts Question 5 5. Examine Rock 3 in the Lab Rock Kit . Which one of the geologist’s groups of minerals mostly makes up this rock? What observation did you use to make your interpretation? iron-rich silicates, because it is mostly dark in color iron-free silicates, because it is mostly light in color other, because it has shiny pieces in it 0 / 1 pts Question 6 Incorrect Incorrect 6. Compare Rock 3, Rock 1, and Rock 9. Which of those rocks is made up of the highest percentage of iron-rich silicate minerals?
