What is a chemical reaction that happens in everyday life?
Examples of chemical reactions in everyday life include photosynthesis, rust, baking, digestion, combustion, chemical batteries, fermentation, and washing with soap and water.
Chemical reactions occur everywhere in the world around you, not just in a chemistry lab..
What are 4 examples of chemical changes?
Examples of Chemical ChangesBurning wood.Souring milk.Mixing acid and base.Digesting food.Cooking an egg.Heating sugar to form caramel.Baking a cake.Rusting of iron.
Which are the most common chemical reactions in the body?
In human body the most common or you can say usual chemical reaction is respiration. Respiration is simply gaseous exchange, with release of energy. It can be stated as in oxidation reaction, where which oxygen from air get absorbed and mixed with food and then it produces energy.

What is a simple chemical reaction?
Examples of Simple Chemical Reactions. A chemical reaction occurs when a chemical or chemicals (the reactants) convert into another substance (the product). These reactions happen during cooking, cleaning, driving, and processes occurring inside your body, among others.
What is a chemical reaction explain with an example?
A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

What is the most important chemical change?
PhotosynthesisAttempting to understand the most important chemical reaction on the planet: Photosynthesis. Photosynthesis is the engine of life. The synthesis of organic compounds made possible by coupling light to the splitting of water is probably the most important set of chemical reactions on the planet.
What is the most powerful chemical?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
