“An acid-base titration is represented by the chemical equation below. CsOH (aq) + HBr (aq) - CsBr (aq) + H20 (1)
In the titration, 15.0 mL of CsOH solution is neutralized
38.2 mL of 0.250 M HBr solution. What is the molarity of the CsOH solution?”

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
