Answer
Magnesium carbonate
Explanation
## Step 1:First, let's understand what a metal carbonate is. A metal carbonate is a compound that consists of a metal cation and the carbonate anion (CO3^2-). ## Step 2:Now, let's analyze each option. ## Step 3:The first option is Magnesium carbonate. This compound consists of the metal Magnesium (Mg) and the carbonate anion (CO3^2-), which fits the definition of a metal carbonate.## Step 4:The second option is Magnesium. This is a metal, but it does not contain the carbonate anion, so it is not a metal carbonate.## Step 5:The third option is Magnesium hydroxide. This compound consists of the metal Magnesium and the hydroxide anion (OH^-). It does not contain the carbonate anion, so it is not a metal carbonate.## Step 6:The fourth option is Magnesium oxide. This compound consists of the metal Magnesium and the oxide anion (O^2-). It does not contain the carbonate anion, so it is not a metal carbonate.
