So the equation would be
4 Fe + 3 O2 = 2 Fe2O3
(95.64)×(1/32)x (2/3)×(156.69/1)
The atomic symbol for Iron is Fe, as the Latin word for Iron is <em>ferrum</em>.
Answer:
3
Explanation:
you must multiply everything out till everything is equal on both sides
Carbon have 4 valence electron
The electron configuration of C is : 1s2 2s2 2ps
the outer most s and p orbital contains 4 electrons and these are the valence electron of C atom
Key: to determine the valence electron of an element, you have to refer to the group it is located in, in the periodic table. (C is in group 4 (or 14) so VE = 4)
hope its clear enough
