Zinc Carbonate Compounds and Properties

The video tutorial explains how to name the compound ZnCO3. It begins by identifying ZnCO3 as a ternary ionic compound composed of a metal, zinc, and a polyatomic ion, carbonate. The tutorial outlines the process of naming the compound by first identifying the metal and then recognizing the carbonate ion, which has a 2- charge. The name of the compound is given as zinc carbonate. Additionally, the video explains how to write the formula for zinc carbonate, noting that the zinc ion has a 2+ charge, which balances with the carbonate ion's 2- charge, resulting in the formula ZnCO3.
