Na2SO4 is the salt that is produced.
If you look at the question, it asking which is produced so the answer must be on the product side of the reaction (to the right of the arrow).
You should also recognize that 2H2O is water, and water is not a salt.
Therefore the only other choice is Na2SO4.
Answer:
A qualitative correlation between the extent of interaction between various Lewis acids and bases has been achieved by classifying the acids or bases into two classes: hard and soft in his theory of Hard and Soft Acids and Bases – HSAB. Acid-base reactions are then treated by the general principle that hard acids prefer to combine with hard bases and soft acids prefer to combine with soft bases (and vice versa). The criterion of hardness (or softness) is ascribed to the “hardness” of the electron cloud associated with any species. A firmly held electron-cloud with low polarizability makes a species “hard”, while an easily polarizable electron cloud characterizes the species as “soft”. A third category with intermediate character appears in the borderline.

Volume= h*l*w
2*3*2=12cm
You're answer is 12cm. Hope it helps!
The answer should be chloride and sodium
Answer:
We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.
So 1 g water will contain 1/18 moles of H2O molecules.
Now 15 g of water will contain 15/18 moles of H2O.
So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.
