No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
No
Chemical property, it cannot be decomposed by ordinary chemical change.
It is a chemical change because sugar is decomposed.
Yes, this change is possible.
Antimony
no
No
Chemical property, it cannot be decomposed by ordinary chemical change.
Decomposition is a chemical change because the nature of the compound that has decomposed is now a different or several different chemicals after decomposition. It cannot be converted back to what it was, and so this is a chemical change.
It is a chemical change because sugar is decomposed.
Yes, this change is possible.
The chemical equation is:2 NaN3 = 2 Na + 3N2
Antimony
1 sodium
Sodium is a chemical element, not a change.
It is a chemical change because some compounds from bread are thermally decomposed.
All except neon, with atomic symbol Ne, of the entities shown the question by their chemical formulas or symbols can be decomposed by chemical change.
