Chemical reaction equations are a powerful tool, but only if they're balanced! In this simulation, you will learn how to decipher chemical equations and practice balancing them. You will learn the difference between reactants and products and how the rule of mass conservation guides us on how to balance them. With mass conservation in mind, you will balance each equation to perfection so you can get to the launch room and fire a missile toward an incoming comet!

Visualize the rule of mass conservation

Mass conservation is at the core of chemical equation balancing. To help you visualize this principle, you will get three-dimensional molecules that you can place on a scale. Can you figure out how many molecules to put on each side of the scales to give the same number of atoms on both sides?

Balance the chemical reaction equations

With Labster's custom-made chemical equation balancer, you'll be balancing equations like a pro in no time! To balance your chemical equations, you must provide the correct coefficients, and the balancer will count the number of each element on the reactant and product sides for you. Additionally, with correct coefficients, the equation balancer can synthesize real substances from the reactants which you will use to solve problems ahead.

Save the base from an incoming threat!

With the impending doom of an approaching comet, you must launch a defense quickly! For each equation you balance correctly, you are one step closer to launching a comet-destroying missile. Can you get all those coefficients right before it's too late?
