Answer:
CO₃²⁻ + Zn²⁺ → ZnCO₃(s)
Explanation:
The net ionic equation is defined as a chemical equation for a reaction that lists only those species participating in the reaction.
In the reaction of sodium carbonate (Na₂CO₃) with zinc iodide (ZnI₂) that produce solid zinc carbonate (ZnCO₃) and a solution of sodium iodide (NaI) the formula is:
2Na⁺ + CO₃²⁻ + Zn²⁺ + 2I⁻ → ZnCO₃(s) + 2Na⁺ + 2I⁻
The net ionic equation is:
<em> CO₃²⁻ + Zn²⁺ → ZnCO₃(s)</em>

Answer:
No, the pH scale can not be utilized for all types of acids known
Explanation:
The pH scale is a scale that shows the degree of acidity or alkalinity of a substance. The pH scale is graduated from 0-14. The pH scale is mostly applied to Arrhenius acids. Recall that in the Arrhenius definition, an acid produces hydrogen ion in solution while a base produces hydroxide ion in solution. Hence we could easily measure or calculate the pH and pOH of Arrhenius acids. Arrhenius acids apply mostly to acid-base discussion in Aqueous media.
Beyond aqueous media, we can still apply the Brownstead-Lowry and Lewis definitions for acid and base. Some of these substances to which we apply these other definitions of acid and base do not necessarily contain hydrogen or hydroxide ions hence the pH scale can not be utilized in discussing their acid-base properties, hence the answer.
Answer:
Electrons
Explanation:
The particles found in the cloud surrounding the nucleus of an atom are the electrons.
These particles occupies the bulk volume of the atom.
- Electrons were first discovered by J.J Thomson from his experiment on the gas discharge tube.
- These particles carries a negative charge on them.
- They have a mass of 9.11 x 10³¹kg
Answer: The kinetic energy of solids is limited to vibrational energies..the particles are tightly bound in their crystalline structure and can only bend, flex, and vibrate about relatively fixed position. When vibrational energies exceed the strength of the force holding the particles together, the crystal structure collapses and we say the material melted. The particles can now have, in addition to its vibrational energies, rotational energy. Chunks of the collapsed crystal can, like a ball floating in water, rotate without showing much translational energy. Generally, we associate solids with vibrational kinetic energy, liquids with rotational kinetic energy, and gases with translational kinetic energy. Actually though, liquids have both vibrational and rotational energies, and gases have all three.
