I'm in need of some help. No links. Real answers, please and thank you How many grams of AlCl3 are needed to completely react with 2.25 of NaOH?

a electronegativity decreases beacuse the size of nucleus is bigger.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

i dont know the answe
