Answer:

Equations REPRESENT chemical reactions...........whose behaviour must be established by experiment.

Explanation:

And chemical reactions follow TWO ABSOLUTE RULES :

#"1. Mass is conserved."#

#"2. Charge is conserved."#

It follows that our representation of chemical reactions CONSERVE mass and charge.

For redox reactions, see here, for the half equation method.. For combustion reactions, see here, and for the use of stoichiometry in our daily life, see here.

But remember that chemical equations represent actual experiments, whose behaviour and performance must be observed and assessed.
