3. A is a laboratory method used to determine the
concentration of an acid or a in solution by performing a reaction with a standard solution. 4. At the of the titration, the indicator changes color, which
indicates neutralization. Once neutralized, moles of and moles of are equal. 5. In a titration of HCl with NaOH, 100.0 mL of the base was required to
neutralize 20.0 mL of 5.0 M HCl. What is the molarity of the NaOH? (Be sure to write the neutralization reaction.)

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
