<h3>Answer:</h3>

B. The object moves some distance

<h3>Explanation:</h3>

Work is the product of force and distance.

Work is done on an object when a force is applied on the object making it move some distance.
For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.
Applying a force on an object without making it move some distance then there is no work done.
Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.

Explanation:

The<em> molecular formula for the involved species</em> are:

Sulfur trioxide = SO₃. ("trioxide" indicates the presence of 3 oxygen atoms).

Water = H₂O

Sulfuric acid = H₂SO₄
