Bubbles, and heat change are examples of chemical reactions. When a chemical reaction happens, a compound is formed. It cant be separated. Another example could be change of colour.
-making caramel sauce
-getting a suntan
Everywhere you look you'll see a chemical reaction!
Everything from breathing to turning the lights on.
Striking a match is an example of a chemical reaction. Digestion is another example.
Some examples of a chemical reaction occurring would be 1. Precipitate forming2. Color change
3. Production of a gas
4. Change in temperature
Preparation of sodium chloride:
NaOH + HCl = NaCl + H2O
Salts are obtained by a neutralization reaction, between an acid and a base.
Photosynthesis.
Der sker ikke en skid og metanen lugter stadig af lort.
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Examples of chemical properties: flammability, reaction with oxygen, valence, toxicity, stability, electronegativity etc.
Electrocution, fire and chemical reaction
well the chemical reaction is cooking not physical

Substances that undergo chemical change are called reactants.
Energy that is stored into something and released by a chemical reaction is known as chemical energy. Some examples of these are batteries, gasoline, coal, and food.
Nope - they're an example of a chemical reaction.
The reaction between hydrogen and oxygen to form water is represented by the following equation. 2 H2 + O2 2 H2O
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Examples of chemical changes: combustion, corrosion, fermentation, photochemical reaction, polymerization.
Examples of chemical properties: flammability, reaction with oxygen, valence, toxicity, stability, electronegativity etc.
Examples: cooking, washing, burning a fuel.
