Vertical columns are called groups, or families.
They share similar chemical properties.

Answer:
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Explanation:
A strong electrolyte is a substance that dissolves in water, dissociating in its ions, and making the solution an electric conductor. The conduction will happen because of the presence of the ions. The dissociation will be complete and irreversible.
The chromium (II) nitrate is formed by the cation chromium (II), Cr⁺², and the anion nitrate, NO₃⁻, so it is the compound Cr(NO₃)₂.
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Answer:
The answer is D. The concentrations are different and the reactions are different, so the cell potential is 0.00 volts.
Explanation:
A concentration cell is an electrolytic cell that is comprised of two half-cells with the same electrodes, but differing in concentrations. A concentration cell acts to dilute the more concentrated solution and concentrate the more dilute solution, creating a voltage as the cell reaches an equilibrium.
<h3>Answer:</h3>
Heterogeneous mixture
<h3>Explanation:</h3>
The easiest way of defining Heterogeneous mixture is that it is mixture in which the composition of components is not uniform. Also, the substances present in this mixture are visible to naked eye. In fact, the size of solutes in heterogeneous mixture is greater as compared to that the sizes of solutes in homogeneous solutions. hence in salad dressing the oil, vinegar and spices are all visible and can easily be seen by naked eye.
