On lab day. milania did an experiment with two solids: potassium iodide and silver nitrate. milania measured and recorded the mass, solubility, melting point, and calculated
the density of potassium iodide and silver nitrate before mixing them together. she then calculated the same properties of solid a which resulted after she mixed
potassium iodide and silver nitrate. her experimental results are shown below
a. it is a physical change because mass of solid a is similar but o the masses of potassium iodide and silver nitrate
b. it is a physical change because the solubility of solid a is different than potassium iodide and silver nitrate
c. it is a chemical change because the densities of potassium iodide and silver nitrate are the same
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
