Question 2
1 pts
Examine the chemical formula for these two minerals:
β’ Biotite mica [K(Mg,Fe)AlSi3010(OH)2]
β’ Muscovite mica [KAI AISI3010(OH)2]
They both form sheet silicate structures with mineral sheets that flake off. Based on their chemical formula predict how they are different in appearance and explain it
