What is the name of #As_2S_3#?

Question

HIX Tutor · Accepted Answer

undefined That's a great question! Let's break it down together.

1. **Identify the elements**: There are two elements here: arsenic (As) and sulfur (S).
2. **Count the atoms**: There are 2 arsenic atoms and 3 sulfur atoms.
3. **Naming the compound**: When naming compounds, we place the name of the first element first, then the second element.
4. **Use suffixes**: For sulfur, we change it to "sulfide."

Putting it all together, As₂S₃ is called **arsenic trisulfide**.

Does that make sense?

Luna Chen · Answer

The name is diarsenic trisulfide.

#"As"_2"S"_3# is a binary molecular compound : It consists of only two elements and contains no ions. The rules for naming the compound are: 1. Write the names of the elements in the same order as in the compound. This gives the name arsenic sulfur. 2. Replace the name of the second element with its root followed by the suffix -ide. The root of #"sulf"#ur is #"sulf-"#. This gives the name arsenic sulfide. 3 Indicate the numbers of each atom by a multiplying prefix The multiplying prefix for two is #di"-"#, and the multiplying prefix for three is #tri"-"#. Thus, the name of #"As"_2"S"_3# becomes #bb"diarsenic trisulfide"#.
