Answer:
none
Explanation:
It is given that there are 3 cats.
Each of the cats die with different diseases. One of cats died due to heart failure, the second cats died because of brain tumor and the third cat died due to an experiment gone wrong.
So there are none of the cats left out. All the cats died due to different reasons.
THE MOLAR MASS OF FLUORINE IS 35G/MOL
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.
