The value of Ksp for PbI2 is 1.4 × 10–8. What mass (expressed in grams) of solid potassium iodide, KI, must be added to 200. mL of 0.00026-M Pb(NO3)2(aq) to cause PbI2 to precipitate? Assume no volume change when adding the solid KI.

Which of the following is a conclusion that resulted from ernest rutherford’s scattering experiment? (will mark brainliest) a. the nucleus is negatively charged b. the atom is a dense solid and is indivisible c. the mass is conserved when atoms react chemically d. the nucleus is very small and the atom is mostly empty space
