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
The chemical equation sodium + chlorine -> sodium chloride represents a chemical reaction called a combination or synthesis reaction. In this reaction, two elements (sodium and chlorine) combine to form a single compound (sodium chloride) by bonding together.
A balanced chemical equation allows you to determine the ratio of reactants consumed and products produced in a chemical reaction. It also allows you to calculate the amounts of substances involved in the reaction based on the stoichiometry of the equation.
The chemical equation sodium + chlorine → sodium chloride represents a combination reaction, where two or more substances combine to form a single product. In this case, sodium and chlorine react to form sodium chloride.

The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.
The chemical equation sodium + chlorine -> sodium chloride represents a chemical reaction called a combination or synthesis reaction. In this reaction, two elements (sodium and chlorine) combine to form a single compound (sodium chloride) by bonding together.
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.
A balanced chemical equation allows you to determine the ratio of reactants consumed and products produced in a chemical reaction. It also allows you to calculate the amounts of substances involved in the reaction based on the stoichiometry of the equation.
Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic reaction.
The chemical equation sodium + chlorine → sodium chloride represents a combination reaction, where two or more substances combine to form a single product. In this case, sodium and chlorine react to form sodium chloride.
A chemical reaction.
By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
A waterfall is not a chemical reaction.
