is a change in matter that produces one or move new substances.
This is a catalyst
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
A reaction that produces heat
A lit sparkler involves both physical and chemical processes. The sparkler itself is a physical object, but when ignited, a chemical reaction occurs as the oxidizers and fuel in the sparkler's composition burn, producing heat, light, and various gases. This combination of physical presence and chemical reaction defines the nature of a lit sparkler.
An endothermic reaction need heat to begin.
Compounds that form after a chemical reaction is complete are called products. The compounds they're made of are called reactants.

A reaction that produces heat
An acid is a substance that donates hydrogen ions in a chemical reaction, typically characterized by a pH less than 7.
An exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that the products have lower energy than the reactants. Exothermic reactions are often characterized by temperature increases, light emission, or sound production.

Chemical reaction
Combustion is a chemical reaction.
No. A chemical reaction is not alive.
