No. Fe (iron) is an element, the simplest type of chemical substance possible, and so it cannot be broken down by chemical means.
no
NO2 or N2
If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
methanolammonia (NH4)ammonia (NH4)
it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
no
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
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.
Yes, H2O can be decomposed by electrolysis. 2H2O --> 2H2 + O2
It is a chemical change because some compounds from bread are thermally decomposed.
Sucrose can be decomposed in glucose and fructose.
