You add whole number coefficients before each substance in the equation as needed until the number of atoms on the reactant side equals the number of atoms on the product side. For example, in the unbalanced equation:
Cu + AlCl3 --> CuCl2 + Al, the number of copper and chlorine atoms on one side does not equal the other side. However, by adding coefficients to make the equation read 3Cu + 2AlCl3 --> 3CuCl2 + 2Al, everything adds up. Things to remember: balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed; and also the coefficients in a balanced chemical equation represent mole ratios.

What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
An expression that uses symbols to describe a chemical reaction?
chemical equations
What do balanced and unbalanced chemical equations share in common?
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
Where are subscripts placed in chemical equations?
Right and down the symbol of a chemical element.
Thermochemical equations are chemical equations that include the of the reaction.?
Termochemical reactions include the enthalpy of reactants and products.
What is the chemical equations of honey?
Honey hasn't chemical equations.
What can chemical equations tell you about a chemical reactions?
Chemical equations describe the products and reactants in a chemical reaction.
What do chemical equations show about compounds and elements?
Chemical equations represent chemical composition of reactants and products and also how does the reaction occur.
What are codes used in chemical equations telling what atoms are part of the equations?
formulas
How do you show chemical reactions in writing?
chemical equations
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
Why do scientists use chemical equations instead of word equations?
its easier
How are chemical reactions abbreviated?
Chemical reactions are abbreviated by their chemical equations.
How are chemical equation helpful?
Chemical equations are representative for chemical reactions.
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Study of chemical equations?
This is chemistry, especially chemical kinetics.
What is a chemical equation balanced does it show?
Chemical equations are representative for chemical reactions.
