There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.
There are no net ionic equations for the given reactions as neither of them forms a precipitate.The correct option is no reaction.
The reactions are as follows:
Ionic equation is defined as a chemical equation which represents electrolytes in aqueous solutions and are expressed as dissociated ions. Ions present in aqueous solutions are stabilized by ion dipole interactions with the water molecules which are present.
An ionic equation can be written for any electrolyte which dissociates and reacts with the polar solvent. In a balanced ionic equation , number and type of atoms on each sides of reaction arrow are same. Even the net charge on both sides of the arrow is same.
There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.Thus, the correct option is no reaction.

The correct answer for above statement is:
Prices don’t show the total cost of reconstruction fuels to each of us personally or to the community as a whole. Remembered as externalities, the unknown costs of fossil fuels aren’t described in their business price, notwithstanding severe consequences on our health and environment.
Concerns over a global dependence on fossil fuels include environmental, economic, and social consequences.
The statement about “Concerns over a global dependence on fossil fuels include environmental, economic, and social consequences” is true. The environmental, economic, and social consequences greatly affects the global dependence.
The isotope 40Ar contains 18 protons, 18 electrons, and 22 neutrons.
The isotope 40Ar refers to the isotope of argon, which has an atomic number of 18.
Since the atomic number represents the number of protons in an atom, we can conclude that the isotope 40Ar contains 18 protons.
Argon is a neutral atom, so the number of electrons also matches the number of protons. Therefore, the isotope 40Ar contains 18 electrons.
To find the number of neutrons, we need to subtract the atomic number (protons) from the mass number (protons + neutrons). The mass number of 40Ar is 40. Subtracting the atomic number of 18 from the mass number gives us:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 40 - 18
Number of neutrons = 22
Therefore, the isotope 40Ar contains 18 protons, 18 electrons, and 22 neutrons.

Answer:
18 protons, 18 electrons, 22 nuetrons
Explanation:
Argon has an atomic # of 18. Atomic #s show the amount of protons and electrons it has. Atomic mass - atomic # = # of nuetrons. 40-18=22
