a) $N_{2}O_{4}$ - Dinitrogen tetroxide b) $ICl_{3}$ - Iodine trichloride c) $SO_{2}$ - Sulfur dioxide d) $P_{2}S_{5}$ - Phosphorus pentasulfide

Work Step by Step

a) The picture has two nitrogen atoms - thus dinitrogen [ Di - two ] , And with them, are 4 oxygen atoms - thus tetroxide [ tetra - four ]. So, the compound is named dintrogen tetroxide. b) The picture contains one iodine atom, and three chlorine atoms, and thus trichloride [ tri - three ]. So, the compound is named iodine trichloride c) There are two oxygen atoms and one sulfur atom, and thus the name Sulfur dioxide [ di - two ] d) Since there are five sulfur atoms, and hence the name phosphorus pentasulfide [penta - five]
