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:
The word "Halloween" comes from All Hallows' Eve and means "hallowed evening."
Halloween's origins can be traced back to the ancient Celtic festival known as Samhain, which was held on November 1 in contemporary calendars. It was believed that on that day, the souls of the dead returned to their homes, so people dressed in costumes and lit bonfires to ward off spirits.
Explanation:
Answer:
Burning of fossil fuels releases a lot of pollutants such as sulphur dioxide and nitrogen dioxide into the atmosphere, and reacts with the water in the atmosphere to form sulphuric acid or nitric acid. Hence, acid rain is formed as that acid comes down from the atmosphere along with the rain.

Answer:
Answer is: Keq = [CO₂].
Explanation:
Balanced chemical reaction: CaCO3(s) ⇄ CaO(s) + CO₂(g).
The equilibrium constant (Keq) is a ratio of the concentration of the products to the concentration of the reactants.
Pure liquids (shown in chemical reactions by appending (l) to the chemical formula) and solids (shown in chemical equations by appending (s) to the chemical formula) not go in to he equilibrium constant expression, only gas state (shown in chemical reactions by appending (g) to the chemical formula) reactants and products go in to the equilibrium constant expression
