Answer:
The concentration is equal to 1.88x10^-5 M
Explanation:
To calculate the concentration of the unknown solution of 0.699 of absorbance, we must make a graph in Excel and obtain the equation that represents the absorbance vs. molar concentration.
graphing the concentration on the "x" axis and the "y" axis of the absorbance and also linearizing, we have the following expression:
y = 37640x - 0.0089
Clearing x, we have:
x = (y + 0.089)/37640 = (0.699 + 0.089)/37640 = 1.88x10^-5 M
Rutherford’s, Bohr’s, and the quantum models say that electrons behave as particles, electron is negatively charged and electrons behave both particles and wave respectively.
<h3>What Rutherford’s, Bohr’s, and the quantum models say about electron?</h3>
Bohr model states that electrons behave as particles, Rutherford's model proposed that the negatively charged electrons surround the nucleus of an atom whereas quantum model explains that the electron has both particle and wave behavior.
So we can conclude that Rutherford’s, Bohr’s, and the quantum models say that electrons behave as particles, electron is negatively charged and electrons behave both particles and wave respectively.

Answer: C) 8 moles
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
According to stoichiometry of the given balanced equation:
2 moles of decomposes to form 2 moles of
Thus 8 moles of decomposes to form= of
Thus 8 moles of are produced from 8 moles of
