Reaction between 36i.5 grans of sodium hydroxide and 100 grams of aluminum sulfate in an aqueous solution. I need a balence eqation. I need to know wich product would precipitate out. If the reaction ends up with 139.5 g of preticipate, how many molicules. And whatever else you think might be important. I will fail chem if I dont get this right

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.
