Question

The compound, (nh4)2s, can be used in analysis for trace amounts of metals present in a sample. what is its name?

Answer 1

Answer: The name of the given compound is ammonium sulfide.

Step-by-step explanation:

We are given a chemical compound having chemical formula of
`(NH_4)_2S`. This is formed by the combination of ammonium
`(NH_4^+)` ions and sulfur
`S^(2-)` ions.

The given compound is an ionic compound because complete transfer of electrons takes place from one atom to another atom.

The nomenclature of ionic compounds is given by:

• Positive ion is written first.
• The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
• In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.

Hence, the name of the given compound is ammonium sulfide.

Answer 2

To name compounds, usually, they are a combination of a metal and a nonmetal, between nonmetals and between metals. The two elements here are ammonium (NH₄) and sulfur (S). These are both nonmetals. When you name the compound, start by ammonium, followed by sulfur plus a suffix of -ide. The compound is ammonium sulfide.
