Question

1 multiple choice 20 points analyze the chemical formula to correcting identify the number of atoms that compromise the given compound. cacl₂ calcium = 1 carbon = 1 lodine = 2 calcium = 1 carbon = 1 lodine = 1 calcium = 1 chlorine = 2 calcium = 2 chlorine = 1

Explanation:

Step1: Analyze the chemical formula

The chemical formula is \(CaCl_2\). In a chemical formula, the subscript after an element symbol indicates the number of atoms of that element. For \(Ca\) (calcium), there is no subscript, which means there is 1 calcium atom. For \(Cl\) (chlorine), the subscript is 2, so there are 2 chlorine atoms.

Answer:

C. Calcium = 1, Chlorine = 2
