Question

Which of the following naming rules would apply to CaCO 3? Question 3 options: polyatomic cation + nonmetal anion(–ide) metal + polyatomic anion metal cation + (roman numeral valence) + nonmetal anion(–ide) metal cation + nonmetal anion(–ide)

Answer 1

Metal + polyatomic anion.The name will be 'Calcium carbonate'.

Step-by-step explanation:

Answer 2

Answer: The correct option is Metal + polyatomic anion.The name will be 'Calcium carbonate'.

Solution:

Salts name is made up two parts:

1. First part is name of cation here present in salt.
2. Second part is name of polyatomic anion like :
   `Cl^-\text{is chloride},SO_4\text{is sulphate}` etc.

So,the name of
`CaCO_3` is calcium carbonate.Here,metal ion in the salt is calcium metal and the anion is polyatomic carbonate ion.
