Step 1:I'll solve this step-by-step:
Step 2:: Identify the ions
- Copper(I) indicates the copper ion has a +1 charge: $$Cu^{+}
- Carbonate ion has a - 2 charge: CO_{3}^{2 -}
Step 3:: Determine the ionic ratio
- To balance the charges, we need 2 copper ions for every 1 carbonate ion - This ensures the total positive and negative charges cancel out
Step 4:: Write the chemical formula
- Formula will be: $$Cu_{2}CO_{3}
- Combine the ions with their subscripts
Final Answer
Key Points: - Copper is in the + 1 oxidation state - Carbonate is a polyatomic ion with a - 2 charge - The formula reflects the charge balance between the ions
