Explanation:

Step1: Write ionic/covalent formulas

Calcium chloride: $\text{CaCl}_2$ (Ca²⁺ + 2 Cl⁻)
Carbon trioxide: $\text{CO}_3$ (1 C + 3 O)
Magnesium oxide: $\text{MgO}$ (Mg²⁺ + O²⁻)
Dinitrogen pentoxide: $\text{N}_2\text{O}_5$ (2 N + 5 O)
Aluminum sulfide: $\text{Al}_2\text{S}_3$ (2 Al³⁺ + 3 S²⁻)
Sulfur hexafluoride: $\text{SF}_6$ (1 S + 6 F)

Step2: Name ionic/covalent compounds

$\text{SrI}_2$: Strontium iodide (Sr²⁺ + I⁻)
$\text{N}_2\text{O}_3$: Dinitrogen trioxide (2 N + 3 O)
$\text{CS}_2$: Carbon disulfide (1 C + 2 S)
$\text{AgF}$: Silver(I) fluoride (Ag⁺ + F⁻)
$\text{Li}_2\text{O}$: Lithium oxide (2 Li⁺ + O²⁻)
$\text{CO}$: Carbon monoxide (1 C + 1 O)

Answer:
