Maya, Arjun, and David are playing a game of 'Chemistry Whiz'. Maya asks, 'What is the cool, shorthand way we use to write down the reactants we use and the products we get in a chemical reaction?'

• Is it the Law of conservation of mass?

• Or, is it the Chemical equation?

• Maybe it's the Odor?

• Or could it be the Density?
