Question

7 multiple choice 10 points what is the name for cuco₃? copper (i) carbonate copper (ii) carbonate copper (ii) trioxycarbide copper (i) carbide

Explanation:

• The carbonate ion ($\text{CO}_3^{2-}$) has a charge of - 2.
• In a neutral compound, the sum of the charges of the ions must be zero. Let the oxidation state of copper be \(x\). For \(\text{CuCO}_3\), we have \(x+( - 2)=0\), so \(x = + 2\).
• The carbonate ion is \(\text{CO}_3^{2-}\), not a carbide (\(\text{C}^{4 -}\)) or trioxycarbide (incorrect naming).

Answer:

copper (II) carbonate
