Final answer:
The stock system names for N2O3, CO, and SO3 are dinitrogen trioxide, carbon monoxide, and sulfur trioxide respectively.
Step-by-step explanation:
The stock system names for the compounds in the given list are as follows:
- N2O3: Dinitrogen trioxide
- CO: Carbon monoxide
- SO3: Sulfur trioxide
The stock system names are based on the oxidation states of the elements in the compounds. In the case of N2O3, the compound has two nitrogen atoms and three oxygen atoms, so it is named dinitrogen trioxide. Carbon monoxide consists of one carbon atom and one oxygen atom, while sulfur trioxide is composed of one sulfur atom and three oxygen atoms.
