These are only 5, but with these you should get the idea of what a chemical change is.
there are many examples of a chemical change.
-burning paper (or anything)
-baking a cake
-cooking an egg
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
a precipitate.
liquid
Physical change - make it frozen ; Chemical change - make it spoiled
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.
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water
