Answer:mixing decomposing
Explanation:
Melting and grinding changes the physical form and mixing decomposing doesn’t
Bohr changed the model of the atom by proposing that electrons travelled in circular orbits with specific energy levels.
Answer:
C The experiment shows that the red substance experienced a chemical change.
Explanation:
Apparently, adding heat caused the red substance to decompose into a gas and a metallic liquid. If it were simply a phase change, the original red substance could be expected to return when the temperature cooled. Because the substance apparently decomposed, it is clearly not an element. At no point in the experiment is there any evidence of a plasma being formed.
The observed decomposition is a chemical change.
Answer:
Color change
Explanation:
If it is a chemical change, then the color will change. Sometimes chemical changes also cause fizzing and bubbling.
