Answer

Explanation:

Step1: Identificar los átomos en el compuesto

El carbonato de calcio tiene 1 átomo de calcio (Ca), 1 átomo de carbono (C) y 3 átomos de oxígeno (O).

Step2: Escribir la fórmula química correcta

Se escribe el símbolo del metal (Ca) primero, luego el del no - metal (C) y después el del otro no - metal (O) con el subíndice que indica el número de átomos. Así, la fórmula química es CaCO₃.

Answer:

C. CaCO₃
