Ag2S forms a black precipitate and CdS forms a dark yellow precipitate. A solution of CdS is prepared by dissolving 0.25 moles of solid CdS in distilled water. When equilibrium is established, a small amount of dark yellow solid remains on the bottom. A 0.25 mol if solid AgNO3 is then stirred into the beaker, and the dark yellow precipitate is replaced with a black precipitate. I. Did the following equilibrium shift after the AgNO3 was added? Explain using 2-3 sentences.

CdS (s) equilibrium arrows Cd 2+ (aq) + S 2- (aq)

II. Which compound has the larger Ksp value? Justify your answer.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answer is a and have a great day
