Answer: Fluorine (see explanation)
Explanation:
Stream “Do We Have a Problem” by Nicki Minaj and Lil Baby coming out 2/4/22
Answer:
Explanation:
A = Absorbance of solution
E = Molar absorptivity
l = Length of cuvette = 1 cm
c = Concentration of solution
Beer's law is given by
The equation of a straight line is given by
Comparing the above equations we get
Value on 
axis = A = Absorbance of solution = 0.23
= Slope of line = El = Molar absorptivity multiplied with length = 
= Value of x axis = c = Concentration of solution
So we get
The molar concentration of the sample is
An element can be represented symbolically in terms of its atomic number and mass number as:
_{Z}^{A}\textrm{X}
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
_{0}^{1}\textrm{n}
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
x(0.5)(320)=(1.2)(48)(325)
160x=18720
x=18720/160
x=117
