<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Precipitate is defined as insoluble solid substance that emerges when two different aqueous solutions are mixed together. It usually settles down at the bottom of the solution after sometime.
For the given chemical equation:
The products formed in the reaction are calcium carbonate and potassium chloride. Out of the two products, one of them is insoluble which is calcium carbonate. Thus, it is considered as a precipitate.
Hence, the correct answer is Option B.
Answer:
The answer to your question is FeS₃
Explanation:
Data
mass of Fe = 3.78g
mass of S = 5.95 g
mass of FeS
Chemical Balanced Reaction
Fe + S ⇒ FeS
Process
1.- Convert the grams to moles
For Iron
55.85g of Fe -------------- 1 mol
3.78 g of Fe ----------- x
x = (3.78 x 1) / 55.85
x = 0.0677 moles
For Sulfur
32 g of S ------------------- 1 mol
5.95 g ------------------ x
x = (5.95 x 1)/32
x = 0.185 moles
2.- Divide by the lowest number of moles
Iron = 0.0677 /0.0677 = 1
Sulfur = 0.185 /0.0677 = 2.73 ≈ 3
3.- Write the empirical formula
FeS₃
Answer:
Turnover number = 113182s⁻¹
Explanation:
Turnover number is a concept used to know the activity of an enzyme. The higher turnover number, the higher activity of the enzime.
Turnover number is defined as:
Turnover number = Rmax / [E]t
As Rmax is 249 μmol⋅L⁻¹⋅s⁻¹ and [E]t is 2.20 nmol⋅L⁻¹
As 1μmol = 1000nmol, Rmax = 249000 nmol⋅L⁻¹⋅s⁻¹. Replacing:
Turnover number = 249000 nmol⋅L⁻¹⋅s⁻¹ / 2.20 nmol⋅L⁻¹
<h3>Turnover number = 113182s⁻¹</h3>
Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
