Answer:
There is two iron atoms.
Explanation:
The formula iron oxide is Fe2O3 F e 2 O 3 therefore there would be two. Hope this helps. :)
1) H2O is able to dissolve both polar molecules and non polar ones
2) due to its extreme polarity it can even dissolve some I onic compounds
3 the h2o molecule itself is small in size
Y : CCP : 4 atoms
X : tetrahedral voids would be 1/3 × 8 = 8/3
so formula would be Y12X8 or Y3X2 !!
