There are only two oxides listed, but one of them decomposes as it turns to vapor.
To determine the molecular formula of the oxide of arsenic in its gaseous state, we can refer to reliable sources such as the WebElements website.
1. Start by searching for the element "arsenic" on the website. You can do this by either using the search bar or browsing the periodic table until you find "As."
2. Once you have located the element, look for the oxides section on the element's page. In this case, you will find information about the different oxides of arsenic.
3. The WebElements website provides a list of the known oxides of arsenic. In this case, you will find that there are two primary oxides listed: arsenic(III) oxide (As2O3) and arsenic(V) oxide (As2O5).
4. Take note that one of the oxides, arsenic(III) oxide (As2O3), decomposes when turned into vapor. This means that it breaks down into smaller components or molecules. However, it is important to note that in the solid state, the formula remains As2O3.
5. As we are specifically looking for the molecular formula of the oxide of arsenic in its gaseous state, we focus on the second oxide, arsenic(V) oxide (As2O5). This means that the molecular formula for the oxide of arsenic in its gaseous state is also As2O5.
In summary, according to the WebElements website, the molecular formula of the oxide of arsenic in its gaseous state is As2O5.
