Final answer:
The correct option is a) 1, 1, 1, 1
Step-by-step explanation:
In a chemical equation, if a molecule does not need to be multiplied, the number 1 is used for its coefficient. In this case, the correct option is a) 1, 1, 1, 1.
- Box 1: Represents the coefficient for the first reactant.
- Box 2: Represents the coefficient for the second reactant.
- Box 3: Represents the coefficient for the first product.
- Box 4: Represents the coefficient for the second product.
Since the question specifies that the molecule does not need to be multiplied, all the coefficients are 1.
