Question

which of the following models best demonstrates a balanced chemical equation?

Explanation:

Step1: Count reactant/product atoms (Model F)

Reactants: 2 white, 4 dark; Products: 2 white, 4 dark

Step2: Count reactant/product atoms (Model G)

Reactants: 4 white, 2 dark; Products: 3 white, 3 dark

Step3: Count reactant/product atoms (Model H)

Reactants: 2 white, 2 dark; Products: 2 white, 2 dark (unmatched molecule counts)

Step4: Count reactant/product atoms (Model I)

Reactants: 2 white, 2 dark; Products: 2 white, 4 dark

Answer:

F. <The model with 1 white diatomic molecule, 2 dark diatomic molecules reacting to form 2 molecules with 1 white and 2 dark atoms each>
