combustion reaction
The equation CaCO3 -> CaO + CO2 is an example of a decomposition reaction.
To let you know what kind of atoms (and how many) make up certain molecules. For example H2O is a chemical equation for a molecule of water. It shows us that there are 2 atoms of Hydrogen and 1 atom of Oxygen in a water molecule. Hope this help! -Sixth Grade Science Teacher
A waterfall is not a chemical reaction.
When the equation is "balanced", that is, when the number of each kind of atoms involved in the reaction is the same in both the total reactants and the total products.
The given reaction is an example of "synthesis" reaction, in particular one in which two elements react to form a chemical compound.

The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.
We know the composition of the reactants, the products, we can calculate the yield of the reaction etc.
A chemical equation written in symbols is sometimes called a balance equation, because the numbers of each kind of atom have to balance on both sides. If it's written in words it's called a word equation.

Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic 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! ;)
Electrodeposition/electrolysis are the chemical reactions involved in electroplating.
