Lithium Oxide (Li2O) is a highly reactive chemical species which reacts to give electrons to other atoms, following a general reaction scheme of:
Li2O + X → LiX + O2
Data were collected from a series of reactions involving lithium oxide and one other element.
Which statement is best supported by the evidence in the table?
The ionization energy of oxygen is lower than that of boron, beryllium, and lithium.
The electronegativity of oxygen is lower than that of fluorine, carbon, and nitrogen.
The electronegativity of oxygen is higher than that of boron, beryllium, and lithium.

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
