The question is asking the ratio of H to S in H2SO4.
In the following molecular formula, there are 2 hydrogen and 1 sulfur.
This means that the ratio is 2:1.
No, the correct answer is B. Physical change because the identity of the substance does not change.
For example, if you take a piece of paper and tear it in half you actually changed its property because now those pieces of paper have half the weight and and size that they did before you did anything. Now you know its a physical change because its still paper all you have done is change the physical appearance.
