Answer:
Strong attraction between ions and the second one High melting points
Explanation:
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.
