D. It is a chemical change because solubility in water of Solid A is different than the solubility in water or both Potassium Iodide and Silver Nitrate

Explanation:

From the given table which summarizes findings about the experiment, we can conclude that It is a chemical change because solubility in water of Solid A is different than the solubility in water of both Potassium Iodide and Silver Nitrate.

  • A chemical change is a form of change in which new substances are produced.
  • A physical change is one in which the states of matter changes especially the form.

Now we that two soluble substances goes to insoluble product.

  • A substance is soluble when they go into solution with a solvent of the same type.
  • This change from solubility to insolubility of a compound is a typical chemical change.
  • Other forms of changes are just physical changes.
