A balanced equation is when the amount of molecules reacting are equal to the amount of molecules being produced. Chemical equations must be balanced because no energy/mass is ever lost when a reaction takes place. This is because atoms are simply arranged.
B. accurate chemical calculations
False. They are balanced by changing the coefficients.
Atoms
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
balanced.
The number of molecules
Chemical equations are representative for chemical reactions.
Yes
the law of conservation of mass.

Balanced and unbalanced chemical equations have the same elements on both sides, they have just been recombinded to form new products from the reactants.

They are necessary for accurate chemical calculations.
B. accurate chemical calculations
No - they are usually balanced by changing the numbers before the molecules.
