Explanation:

Step1: Name covalent compound 1

Identify elements, use prefixes: $\text{Br}_2\text{S}$ → dibromine monosulfide (or sulfur dibromide, standard is sulfur dibromide)

Step2: Name ionic compound 2

Identify cation/anion: $(\text{NH}_4)_2\text{SO}_4$ → ammonium sulfate

Step3: Name covalent compound 3

Use prefixes for $\text{NO}_2$ → nitrogen dioxide

Step4: Name ionic compound 4

Identify cation charge, anion: $\text{Pb(CO}_3\text{)}_2$ → lead(IV) carbonate

Step5: Name covalent compound 5

Use prefixes for $\text{N}_2\text{O}$ → dinitrogen monoxide

Step6: Name ionic compound 6

Identify cation/anion: $\text{ZnF}_2$ → zinc fluoride

Step7: Name covalent compound 7

Use prefixes for $\text{CCl}_4$ → carbon tetrachloride

Step8: Name covalent compound 8

Use prefixes for $\text{SeH}_2$ → selenium dihydride (or hydrogen selenide, standard is hydrogen selenide)

Step9: Name ionic compound 9

Identify cation/anion: $\text{Al(OH)}_3$ → aluminum hydroxide

Step10: Name ionic compound 10

Identify cation/anion: $\text{K}_2\text{O}$ → potassium oxide

Step11: Write formula 11

Sulfur trioxide: $\text{SO}_3$

Step12: Write formula 12

Tin(II) sulfide: $\text{SnS}$

Step13: Write formula 13

Magnesium acetate: $\text{Mg(C}_2\text{H}_3\text{O}_2\text{)}_2$

Step14: Write formula 14

Phosphorus trihydride: $\text{PH}_3$

Step15: Write formula 15

Cadmium chloride: $\text{CdCl}_2$
