Photosynthesis.
its a chemical reaction. in addition to heat and light, a new gaseous substances are formed
'Thermic' means heat. Thus an 'exothermic' reaction produces heat, while an 'endothermic' reaction absorbs heat.
A chemical reaction.
A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
A waterfall is not a chemical reaction.
The stick of a match contains chemical energy, which is released when the match is struck, causing a chemical reaction that produces heat and light.
double-displacement reaction.

A chemical reaction.
This type of reaction is known as a decomposition reaction, where a compound is broken down into simpler substances by either heat, light, electricity, or a chemical reaction. It is the opposite of a synthesis reaction.
A match has chemical energy stored in the match head from the chemical reaction between the matchstick material and the phosphorus compound. When struck, this chemical energy is converted into heat and light energy through combustion.
An exothermic reaction is one that proceeds with the evolution of heat.
