Thus, we can conclude that sugars digested by saliva is a chemical change.
Infinite number of times
Explanation:
For an iron to stop being an iron, it must be completely broken and destroyed via a nuclear reaction.
Physical and chemical activities does not cause the transmutation of substances. They only reduce them into bits.
- The smallest and thinnest cut from the mass of iron will still have a lot of atom.
- In a mole of substance there are about 6.02 x 10²³atoms
- Atoms are the smallest particle of any substance.
- It is impossible to splits a substance into its atom.
- The are very small and microscopic.
- Only nuclear transmutation causes an atom to change and this will eventually change the atom into another.
