Answer:
boron aluminum gallium indium
Explanation:
hope this helps you
When 1 mol of Cr2O3 has 2 mol of Cr, So we can easily get the number of moles of Cr in 2.16 mol of CrO3 by:
Cr → Cr2O3
2 mol→ 1 Mol
X → 2.16 Mol
So X (the no. of mol of Cr ) = 2 Mol * 2.16 Mol = 4.32 Mol
It has 8 valence electrons because the charge is -2.
