reageerimisvõrrand

Reageerimisvõrrand is the Estonian term for a chemical equation. A chemical equation is a symbolic representation of a chemical reaction. It shows the reactants, which are the substances that react, and the products, which are the substances formed as a result of the reaction. The reactants are typically written on the left side of an arrow, and the products are written on the right side. The arrow indicates the direction of the reaction.

For example, the formation of water from hydrogen and oxygen is represented by the equation 2H₂ + O₂ → 2H₂O. In this equation, H₂ (hydrogen) and O₂ (oxygen) are the reactants, and H₂O (water) is the product. The numbers in front of the chemical formulas, known as stoichiometric coefficients, indicate the relative amounts of each substance involved in the reaction. These coefficients ensure that the equation is balanced, meaning that the number of atoms of each element is the same on both sides of the equation, adhering to the law of conservation of mass.

Chemical equations provide a concise way to communicate the essential information about a chemical transformation, including the identities of the substances involved and their relative proportions. They are fundamental tools in chemistry for understanding, predicting, and quantifying chemical processes. Different types of reactions, such as synthesis, decomposition, combustion, and acid-base reactions, are all represented using chemical equations.
