Yea same I tried so hard I think you need to get a expert or look this up on a website or something
<span>Fluorine
For the group 17 elements (Halogens), the ionization energy decreases as the period increases (the elements become less reactive). And since of the 4 elements given, fluorine is from the lowest period, it has the highest ionization energy.</span>
2 Cu + O2 = 2 CuO
2 moles Cu ----------- 1 mole O2
moles Cu -------------- 7.25 moles O2
moles Cu =7.25 * 2 / 1
moles Cu = 14.5 / 1 => 14.5 moles
