G[mcquarrie 22-7] the value of ksp for pbcro4(s) in equilibrium with water at 25◦c is 2.8 · 10−13m2 . write the chemical equation that represents the solubility equilibrium for pbcro4(s) and calculate its solubility in grams per liter in water at 25◦c.

150.0 grams of asf3 were reacted with 180.0 g of ccl4 to produce ascl3 and ccl2f2. if the actual yield of ccl2f2 was 127 g, what is the percent yield?

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.
