The volume of a 0.40 M Mg(NO3)2 solution contains 89g of Mg(NO3)2 is 1.5 L.
Solution is defined as a particular kind of homogenous combination made up of two or more different ingredients. Solute refers to the material that dissolves. Solvents are described as substances that do not dissolve. The substance known as salt water is a solution. A solute and a solvent combine to produce a solution; this is a physical, not a chemical process. A solution is produced when one substance splits apart or dissolves into another.
To calculate this, subtract 89g from 148.3g/mol, the molar mass of magnesium nitrate.
= 89 / 148.3
= 0.6 mole of magnesium nitrate
The volume of solution can be as
= 0.6 moles / 0.40 M
= 1.5 liter.
Thus, the volume of a 0.40 M Mg(NO3)2 solution contains 89g of Mg(NO3)2 is 1.5 L.

Subatomic particles are particles smaller than an atom. Therefore, any element or matter larger than these particles such as molecules, compounds, or cells can be considered as non-examples.
The question asks for non-examples of subatomic particles, that is, elements that do not fall within the category of subatomic particles. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons. Therefore, any element or matter larger than an atom would be a non-example of a subatomic particle.
Examples of non-examples include molecules like water (H2O), oxygen (O2), or carbon dioxide (CO2). These are made up of multiple atoms and thus are larger than individual subatomic particles. Similarly, compounds like salt (NaCl) or sugar (C12H22O11) are also non-examples because they are made of multiple atoms as well. Cells, the basic structural units of living organisms, are much larger than subatomic particles and also represent non-examples.

Vinegar (acetic acid solution) is a polar substance, whereas olive oil is non polar in nature. Like dissolves like. A polar substance cannot dissolve in a non polar compound. Therefore, vinegar which is polar is not soluble in olive oil, a non polar substance. Hence, in a salad dressing olive oil separates out from vinegar.
Added salt would dissolve in vinegar solution as salt, a polar substance which is chemically, sodium chloride is an ionic substance. It can dissolve in the polar vinegar solution but not olive oil.
Answer:
one more proton
Explanation:
The symbol for phosphorous is P; it is element 15 on the Periodic Table. That
means phosphorous-31 has 15 protons. The symbol for sulfur is S; it is
element 16 on the Periodic Table. Sulfur-32 has 16 protons.
