Final answer:
To balance the equation BF3 + Li2(SO3), the correct answer is BF3 + Li2(SO3) (option B).
Step-by-step explanation:
To balance the equation BF3 + Li2(SO3), we need to ensure that the number of atoms on both sides of the equation is the same. Firstly, we'll count the number of atoms for each element: B - 1 on the left and 1 on the right, F - 3 on the left and 3 on the right, Li - 2 on the left and 2 on the right, and S - 1 on the left and 1 on the right.
Since the number of atoms is already balanced, the correct answer is BF3 + Li2(SO3) (option B).
