Answer: there is more atoms of each element on the right.
Explanation:
On the left of the arrow you have:
Si-1
F-4
H-4
O-2
On the right of the arrow you have:
Si-3
F-6
H-8
O-4
A balanced equation always has the same amount of each element on the left of the arrow (the reactants) as the right (the products). This isn’t balanced because you have a lot more of each element on the right.
