What is present in solution Barney is carrying an open container containing 0.05 moles of solid sodium acetate across the lab, but he trips and spills the contents of the container into a beaker containing 1.0 L of 0.1 M acetic acid solution (at 298 K). Assuming that the addition of sodium acetate does not change the volume of the solution, what is the final concentration of protons in the mixture

Harvey mixes two liquids. which observation of the new mixture most likely indicates a precipitate is forming?

Explain why pure hydrogen cyanide does not conduct electricity, but become a conductor when it is dissolved in water? (at room temp, pure hcn exists as a volatile liquid)

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
