Crystalline silica is hazardous when small particles are
inhaled. They can penetrate deep into the lungs and cause disabling and
sometimes fatal lung diseases including silicosis, lung cancer and kidney
disease. The particles of crystalline silica enters the lungs and causes the
formation of scar tissue known as silicosis, thus reducing the lungs’ ability
to take in oxygen.
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).

Explanation:
706000 in scientific notation is 7.06x10^5
Answer:
They are same.
Explanation:
These are the same measurement; there is no difference in volume. The primary difference is that milliliters are used for fluid amounts while cubic centimeters are used for solids. No matter what is being measured, 1 cc always equals 1 mL.
