Which law represent a balanced chemical equation?

Answer: Law of Conservation of Mass
Explanation:
A balanced chemical equation represents the 'Law of Conservation of Mass '
Law of Conservation of Mass states that 'in chemical reaction mass can neither be created nor be destroyed '.The total mass of the reactant in chemical reaction is equal to the total mass of the products formed in a chemical reaction.
For example :
Mass of reactants = Mass of the products
mass of the reactants = 2(2 × 1) + (2 × 16) = 36 g/mol
Mass of the products = 2[(2 × 1 ) + (1 × 16)] = 36 g/mol
As from the above calculations, we find that the mass of the reactants is equal to the mass of the products. Hence, this equation follows law of conservation of mass.

B. Distance [the red line] is a scalar quantity reflecting how far an object has traveled. Displacement [the green line] is a vector quantity reflecting how far an object has moved from a point. The key difference is that distance can be any sort of path while displacement is always a vector (or a straight line) between a starting point and a finishing point. Sometimes distance and displacement are equal to one another. Sometimes you have a distance traveled, but zero displacement overall; which is what's going on in your question.
A. The distance that the racecar traveled is indeed 500m. But at the end of the lap, it is right back where it started. So overall, it has been displaced 0m.
