The balanced reaction that describes the reaction of chlorine gas and sodium iodide to produce elemental iodine and sodium chloride in aqueous solution is expressed Cl2+2NaI= I2 + 2NaCl. This kind of reaction is called single replacement reaction where the anion, in this case, is only replaced.
The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

Answer:
0.5 moles
Explanation:
At STP,
<u><em>Every 22.4 L of carbon dioxide contains 1 mole of gas.</em></u>
<u><em /></u>
============================================================
Solving :
⇒ 22.4 L : 1 mole
⇒ 22.4 × 0.5 : 1 × 0.5
⇒ 11.2 L : 0.5 moles
Answer:
I'm purty sure it's 10% Cause that is what my teach said.
Explanation:
Have a good day fern!!!!
True.
Sulfur is in the same column of the periodic table as oxygen, but has electronegativity similar to carbon. ... Hydrogen Bonds (The polarity of a water molecule allows the oxygen of one water molecule to bond weakly to the hydrogen of another water molecule.)
