Respuesta :

First: the coefficients give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of each substance involved in the reaction.

The coefficient in a balanced chemical equation represent the number of atoms or molecules of the substance involved in the reaction.

BALANCED CHEMICAL EQUATION:

  • A balanced chemical reaction means that the number of atoms of each element on both sides of the equation are the same.

  • To balance chemical equations, coefficients are used. Coefficients are numbers placed in front of a compound/molecule in a chemical reaction.

  • The coefficient represents the number of atoms or molecules of the substance involved in the chemical reaction.
