In a chemical reaction, what role do coefficients play when balancing the equation?
In a chemical reaction, what role do coefficients play when balancing the equation?
- They determine the state of matter (solid, liquid, gas) of the substances involved.
- They represent the number of atoms in a molecule.
- They indicate the speed of the reaction.
- They are whole numbers placed in front of reactants or products to ensure the conservation of mass. (correct)
