C=4
The charge for the carbonate ion (CO3) is -2. This is because oxygen typically has a charge of -2, and there are three oxygen atoms in the carbonate ion.
The covalent bond is like a molecule and the charge is like an ion.
The formula for barium (Ba) combined with carbonate (CO3) is BaCO3. In this compound, barium has a charge of +2, while the carbonate ion has a charge of -2, which balances out to form a neutral compound. Thus, one barium ion pairs with one carbonate ion to create barium carbonate.
Calcium carbonate (CaCO₃) has two calcium ions because it is composed of one calcium ion (Ca²⁺) and one carbonate ion (CO₃²⁻). The calcium ion carries a +2 charge, while the carbonate ion carries a -2 charge, making them electrically balanced when combined in a 1:1 ratio. This results in the chemical formula CaCO₃, where the two ions together form a stable compound.
The correct formula for the acid that corresponds with the carbonate ion (CO3^2-) is carbonic acid (H2CO3). This acid forms when carbonate ion accepts two protons (H+) to neutralize its charge and stabilize the compound.
The charge on a carbonate ion is -2; therefore, the ion has two more electrons than protons.
2-
The symbol for carbonate ion is CO3^2-, and it has a charge of 2-.
The charge for the carbonate ion (CO3) is -2. This is because oxygen typically has a charge of -2, and there are three oxygen atoms in the carbonate ion.
The formula for carbonate is CO3^2-, and it has a charge of -2 due to the -2 charge on each oxygen atom. The formula for magnesium ion is Mg^2+, which has a charge of +2 due to the loss of two electrons.
Carbonate ions are double negatively charged (2-)CO32-
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
The covalent bond is like a molecule and the charge is like an ion.
The charge on the polytomic ion cyanide is -1.
The empirical formula for calcium carbonate is CaCO3. It consists of one calcium ion (Ca2+) bonded to one carbonate ion (CO32-) which carries an overall charge of 2-.
