Chemical changes: oxydation, reduction, thermal decomposition, synthesis, bromination, polymerization, etc.
Chemical properties: flammability, corrosion, stability, molecular configuration, reactivity, etc.
Examples of chemical changes of matter include, but are not limited to: color change, formation of a precipitate, formation of a gas, change in energy.
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Helium is chemically inert; it does not combine with any other element.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
Examples: chemical reactivity, flammability, tendency to explode, etc.

To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
a chemical property can be observe when under going a chemical reaction some examples are rusting reactivity wood acid metal water and hydrogen
Examples of the characteristics of matter: state of matter, density, radioactivity, thermal properties, electrical properties, optical properties, chemical composition, etc.
the physical properties-the color of the popcorn ,the mass of it ,,the size,,the weight,,and the shape ,, .........chemical properties-it poped it change from seeds to popcorn.....
Helium is chemically inert; it does not combine with any other element.
Chemical properties: flammability, reactivity with a specified substance, radioactivity, enthalphy change of formation, whether it is acidic or basic (pH)Physical properties: melting point, boiling point, density, color, electrical conductivityFor more of chemical and physical properties, see the two related links below under "Sources and related links".
