The video tutorial explains how to write the formula for copper(I) carbonate. It begins by identifying copper and carbonate ions, noting that carbonate is a polyatomic ion. The tutorial then discusses the nature of ionic compounds and the importance of charge balance. Using the crisscross method, the video demonstrates how to derive the formula Cu2CO3. Finally, it verifies the formula by checking the charge balance, ensuring the compound is neutral.
