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 equation CaCO3 -> CaO + CO2 is an example of a decomposition reaction.
A word equation represents a chemical reaction by using names of the reactants and products rather than chemical formulas. It illustrates the transformation of substances during the reaction, indicating how reactants are converted into products. For example, the reaction of hydrogen and oxygen to form water can be expressed as "hydrogen + oxygen → water." This format provides a clear, conceptual understanding of the reaction without delving into the specifics of chemical notation.

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.
When the number of atoms of each kind on the left side of a chemical equation is equal to the number of atoms of each kind on the right side, the equation is said to be balanced. This means that the law of conservation of mass is upheld, indicating that matter is neither created nor destroyed during the chemical reaction. A balanced equation accurately represents the reactants and products involved in the reaction.
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.
