What is Chemical Reaction?
A Chemical Reaction is a process that occurs when two or more molecules interact to form a new product.
Example:
Blow the balloon with backing soda and vinegar water
Baking soda + vinegar water → Carbon Dioxide (gas) + water+ ..
Photosynthesis
carbon dioxide + water (H2O) → Glucose (zat gula) + Oxygen
Iron rust reaction
Iron (Fe) + Oxygen (O2) → Rust (Fe2O3)
Compounds that interact are called reactants, whereas the newly formed compounds are called products.
