A student is titrating 25.00 ml of a weak monoprotic acid solution with an unknown concentration. When setting up the experiment, the student inadvertently uses another team's solution of NaOH. The solution used has a lower concentration than the solution standardized by the student. Select all of the following statements that are true.
a) The pH at the equivalence point will be the same
b) The error will result in a calculated concentration that is higher than the actual concentration
c) You will be able to identify the acid based on the pka value that is determined from the titration curve
d) The pH at the 1/2 equivalence point will be the same
e) The titration will require less volume to react the equivalence point than if the student used their standardized solution

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
