Answer:
Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.
The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.
Explanation:
383 mL of 3.50 M muriatic acid solution
Explanation:
First we calculate the number of moles of HCl:
number of moles = mass / molecular weight
number of moles of HCl = 47.7 / 35.5 = 1.34 moles
Now to determine the volume of the 3.50 M muriatic acid (clorhidric acid) solution, we use the following formula:
molar concentration = number of moles / volume (L)
volume (L) = number of moles / molar concentration
volume of the muriatic acid solution = 1.34 / 3.5 = 0.383 L = 383 mL
