Silver iodide flares release nuclei in numbers of the order of how many per gram of agent?

  • A.about 10 to the power of 30
  • B.about 10 to the 13
  • C.about 100
  • D.about 10 thousand

Answer: B

A single gram yields an enormous number of active nuclei at suitable temperatures. This is why the mass of agent required for a large operation remains comparatively modest. A few kilograms can treat a substantial cloud volume.
