A chemical reaction happens when substances change and form something new. Explore the signs of reactions, the fire triangle, reaction types, and balancing equations! ⚗️
It is a process where reactants change into products (new substances).
Bubbles, light, heat, color change, odor change, and solid formation can be signs of a reaction.
Fire needs Fuel, Heat, and Oxygen. Remove one and fire stops.
Combination, decomposition, single displacement, double displacement, combustion, and acid-base.
We balance to follow the law of conservation of mass — same atoms on both sides.
