Consider these compounds: A. PbBr2 B. Ag,Cro4 C. Pb3(PO4)2 D. Ca3(PO4)2 Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that zinc phosphate is more soluble than phosphate is less soluble than and zinc It is not possible to determine whether zinc phosphate is more or less soluble than | by simply comparing Ksp values.

Consider the molecule tetrahydrocannabinol (?21?30?2), or THC To be legal at the federal level, CBD oil may have no more than 0.3% THC by mass. (That is, a 1-g sample of CBD oil may contain no more than 3 mg of THC.) Assuming the density of CBD oil is 0.95 g/mL, what is the maximum number of moles of THC that may legally be present in 100-mL of CBD oil?
