5. two minerals have different physical properties, but each contain silicate tetrahedrons. what is true of both minerals? a. they have the same density b. they both will fizz with acid c. they contain silicon and oxygen d. they are the same mineral
Answer
# Answer:
C. They contain silicon and oxygen
# Brief Explanation:
A silicate tetrahedron is composed of silicon and oxygen atoms. Just because two minerals have silicate tetrahedrons doesn't mean they have the same density (a), will fizz with acid (b as this is characteristic of carbonates usually), or are the same mineral (d since they have different physical - properties).
