Answer: The correct answer is option (A).
Explanation:
General representation of an element:
A= Atomic mass of the element of X.
Z = Atomic number of the element of X
X = symbol of the element.
According to Law of Conservation of Mass:
A = 244
Charge is balanced on both the sides:
Z = 97
The element with the atomic number 97 is Berkelium. Hence, the correct answer is option (A).
Answer:
The concentration is
Explanation:
From the question we are told that
The absorbance is
The length is
Generally absorbance is mathematically represented as
where is the molar absorptivity of FeSCN2 with a value
and is the equilibrium concentration of FeSCN2
So
substituting values
