Which of the following best explains how the results of Rutherford’s experiment affected Thomson’s widely-accepted atomic model?
hichkok12 [17]

Explanation:

Thomson's suggested the plum pudding model of the atom in which the atomic space is made up of electrons surround by positive charges.

Rutherford in his gold foil experiment revised the plum pudding model of the atom;

  • He discovered that most of the alpha particles passed through the foil while a few of them were deflected back.
  • To explain this observation, he suggested the atomic model of the atom.
  • In this model, an atom is made up of a small positively charged center where nearly all the mass is concentrated.
  • Surrounding the nucleus is the extranuclear part made up of electrons.

A 10.0-milliliter sample of NaOH(aq) is neutralized by 40.0 milliliters of 0.50 M HCl. What is the molarity of the NaOH(aq)?
Ludmilka [50]
\frac{10 mL}{1000 mL}  = 0.01 L

\frac{40mL}{1000mL} =0.04L

M _{1} V_{1}=M_{2}V_{2}

M_{1}(0.01)=(0.50)(0.04)

M_{1}(0.01)=0.02

M_{1}= \frac{0.02}{0.01}

M_{1}=2
