How many grams of Al2O3 are needed to produce 76 grams of oxygen gas 2Al2O3=4Al + 3O2

well in order to answer this question you have to provide more information < 3

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
