O4S2H

H2SO4

S2OH4

SO4H

Answer 1

For Question 1, without seeing the attached picture, I can still provide guidance based on the descriptions of the model types:

• Chemical Formula: Represents substances in terms of their chemical composition. It typically will not have a visual representation.
• Representative Element Series: Refers to a classification of elements in the periodic table, not a molecular model.
• Ball and Stick Model: A 3D representation of molecular structures where atoms are represented by balls and bonds by sticks.
• Plumb Pudding Model: An early atomic model where negatively charged electrons were thought to be distributed within a positively charged "syrup."

If the model in the picture has elements represented as spheres connected by sticks, it would be a Ball and Stick Model.

For Question 2 regarding the chemical formula of sulphuric acid, the correct answer is H2SO4.
