I think A. Molecules interact without bonds breaking
The particle diagram that represents a mixture of three substances is seen in Option 2.
A particle is a small portion of a matter that has both physical and chemical properties.
In inorganic chemistry, a substance refers to a form of matter ( usually particles) that can not be separated by ordinary physical means but by a chemical process.
It can either be:
- an element or a compound.
From the information given, we have:
- an atom of one element
- an atom of a different element
Option 1, 3, and 4 show a particle diagram representing a mixture of only two substances but Only Option 2 shows a particle diagram representing a mixture of three substances.
Therefore, we can conclude that the particle diagram that represents a mixture of three substances is seen in Option 2.

Answer:
3.01×10²⁴ atoms
Explanation:
Our compound is the Na₃PO₄
Sodium phosphate.
We assume, we have 5 moles of the mentioned salt.
1 mol of anything contains 6.02×10²³ atoms.
That's the Avogadro's number. The conversion is:
5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms
