In chemical reactions apply the law of conservation of mass, meaning the number of masses of substances before the reaction must be equal to the amount of the substances after the reaction. For that we need affirmative action to equalize the amount of the chemical reaction of each atom before and after the reaction.
The concept of reaction
Comparison of the coefficient of the reaction shows:
- Comparison of moles that react
- Comparison of the volume of the reacting
A correct response if it satisfies:
- Law of conservation of mass
- The law of conservation of charge
To meet both these laws should be synchronized reaction coefficient.
Chemical equation consists of reactants and products associated with an arrow sign.
Reactant is any substance that at first there and then converted through a chemical reaction.
The product is any substance produced during a chemical reaction.
