Is dissolving salt a chemical change or physical change and why?
Firlakuza [10]

It's a physical change because the composition of the salt hasn't change. Only the change in substance/form has occured. To tell if something has undergone physical change is:

• Melting

• Boiling

• Freezing

• Condensing

• Breaking

• Bending

• Dissolving

• Molecules can change motion and proximity

To tell if something changed chemically:

• Molecules rearrange with other molecules to make new substance

• Can be production of flames

• Color change

• Bubbling/fizzing

• Temp. change

• change in composition

If you want the answer is centimeters is it going to be:
26.281 cm
If it make it easier for you to solve add 6.201 and 7.4 which will equal 13.601. Then add .68 to 13.601 which equals 14.281. Last add 12 to 14.281 which equals 26.281.
