Reactions: Evidence of Chemical Reactions

Chemical reactions are processes where substances change to form new ones with different properties. They are common in everyday life, such as cooking, sitting by a fire, or digesting food. Detecting them can be challenging, but indicators like color change, gas production, precipitate formation, and temperature change can help. Examples include rusting iron, antacid reactions, and heat from igniting matches or magnesium.
