Calculate the number of moles of AL2O3 that are produced when 0.25 moles of fe is produced 2AL(s) + 3FeO(s)> 3Fe(s)+ Al2O3(s)

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
