2 answers:
Answer: Option (3) is the correct answer.
Explanation:
When lattice energy of a compound is more than its hydration energy then the compound is insoluble in water.
Moreover, magnesium carbonate is a precipitate formed by chemical combination of aqueous solutions of magnesium chloride and sodium bicarbonate.
On the other hand, hydration energy of sodium nitrate is more than its lattice energy. Therefore, sodium nitrate is soluble in water and it will readily dissolve.
thus, we can conclude that will remain undissolved and
will dissolve.

Explanation:
The given reaction equation will be as follows.
Now, number of atoms on reactant side are as follows.
- H = 2
- S = 1
- O = 3
Number of atoms on product side are as follows.
- H = 2
- S = 1
- O = 3
Therefore, this equation is balanced since atoms on both reactant and product sides are equal.
Thus, we can conclude that there is one sulfur atom in the products.
