In this experiment, direct titration of a base with acid is not used. instead, a back titration of a base with excess acid will be employed. why?
a. the co2 gas is released during the chemical reaction and is a slow step
b. there is a time delay between the addition of the acid and the completion of the reaction
c. the endpoint of the titration would be unclear because straight titration does not allow enough reaction timed
d. none of the above
e. all of the above

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
