Answer:
moving across te periodic table electronegativity increases.
Explanation:
as we move across a period the effective nuclear charge increases as the number of protons in nucleus increases. due to increase in effective nuclear charge electronegativity increases
33.6 moles are needed to completely react with 84.0 moles of O2
Li because its charge is +1.
