Answer:
B
Explanation:
pure water can accumulate to form ice while pushing the salt particles to be accumulated in the liquid part, because salt particles are more favorable to stay in liquid than ice
so there can still be some salt in the ice between the bonds
John Dalton’s atomic model described atoms as the smallest indivisible part of an element.
<h3>What are atomic models?</h3>
Atomic models are models which are used to represent the structure of the atom.
Different scientists put forward different models to represent the atom.
One of the scientists was John Dalton.
The features of Dalton's atomic model includes:
- atoms are the smallest particle of elements
- atoms are indivisible
- atoms of the same element were the same and atoms if different elements differed in all aspects
Therefore, John Dalton’s atomic model described atoms as the smallest indivisible part of an element.

Answer is: mass of mercury sulfide is 34.9 grams.
Chemical reaction: Hg + S → HgS.
m(Hg) = 30.0 g.
n(Hg) = m(Hg) ÷ M(Hg).
n(Hg) = 30 g ÷ 200.59 g/mol.
n(Hg) = 0.15 mol; amount of substance.
From chemical reaction: n(Hg) : n(HgS) = 1 : 1.
n(HgS) = 0.15 mol.
M(HgS) = 200.59 g/mol + 32.07 g/mol = 232.66 g/mol.
m(HgS) = 0.15 mol · 232.66 g/mol.
m(HgS) = 34.9 g.
