Ammonium sulfide is a compound with the formula (NH4)2S, formed from ammonia and hydrogen sulfide, and is used in various applications such as in analytical chemistry and as a reducing agent. On the other hand, sulfite refers to the sulfite ion, SO3^2-, or compounds containing this ion, and is commonly used as a food preservative. Sulfite can also be involved in various chemical reactions as a reducing or oxidizing agent.

What is the reaction of dilute nitric acid and sodium sufide?
The reaction between dilute nitric acid and sodium sulfide will produce hydrogen sulfide gas, sodium nitrate, and water. The balanced chemical equation for this reaction is 2HNO3 + Na2S → 2NaNO3 + H2S.
Is sulfide an element or a compound?
A sufide is an anion form of the element sulfur. It can form compounds if it combines with other elements. Sulfide on it's own is not a compound, you need a prefix to that like Hydrogen Sulphide. Do not get this mixed up with a sulfate; you can get copper sulphate but not copper sulfide.
What type of ions have name ending in -ide?
Anions have names that end in -ide. Anions are negatively charged ions that are created when atoms gain electrons during chemical reactions. Examples include chloride (Cl−), fluoride (F−), and sulfide (S2−).
How many electrons does sulfide ion have?
A Sulfide ion has a full complement of 8 valence electrons. Sulfur is element 16. It has 6 valence electrons in its outer energy level, however, sufide is S2- so it has gained 2 electrons to fill its outer energy level.
How many atoms are in calcium sufide?
Calcium sulfide (CaS) has two atoms.
What did the Egyptians use for makeup?
the egyptians used kohl which is galena mixed with soot. Galena is lead sufide. They also used malachite which is a copper ore, a carbonate mineral (it has a vibrant green colour). Malachite was imported from the sinai desert.
What is the reaction of dilute nitric acid and sodium sufide?
The reaction between dilute nitric acid and sodium sulfide will produce hydrogen sulfide gas, sodium nitrate, and water. The balanced chemical equation for this reaction is 2HNO3 + Na2S → 2NaNO3 + H2S.
How many potassium ions are needed to balance the charge of one sufide ion?
Two potassium ions are needed to balance the charge of one sulfide ion. Potassium has a +1 charge and sulfide has a -2 charge, so two potassium ions with a +1 charge each are required to balance the -2 charge of the sulfide ion.

How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
Lithium atom: Gain 1 electron Bromine atom: Lose 1 electron Barium ion: Lose 2 electrons Helium atom: No electrons need to be gained or lost
