A box contains 5 white and 4 black balls. Two balls are picked together at random from the box.

What is the probability that these two balls are of different colours ?

1.          1/2
2.          5/18
3.          5/9
4.          1/3

100 mL of 0.0500 M lead(II) nitrate and 200.0 mL of 0.100 M sodium iodide are mixed. Calculate the final concentrations of all ions and the mass of any precipitate. Assume K_sp for PbI₂ = 1.4 x 10^-8.

Need work/steps/concepts, pls make sure answer matches. Ans: [Pb⁺²] = 1.3 x 10^-5M , [I^-] = 3.33 x 10^-2M, [Na⁺] = 0.667 M; [NO₃^-] = 0.0333M, mass PbI₂ = 2.31 g

What is the antonyms of zigzag?

What is the ph of 0.0333M. hno3?

Meteorite On October 9, 1992, a 27-pound meteorite struck a car inPeekskill, NY, creating a dent about 22 deep.

If the initial speed of the meteorite was 500 , what was theaverage force exerted on the meteorite by the car?
