Check out he ball and stick model. Assume the following in the model:

Question

carbon = black
red = oxygen
blue = hydrogen

What is the correct molecular formula?
Responses
A C4H3O5C 4 H 3 O 5
B C4H5O3C 4 H 5 O 3
C C5H3O4C 5 H 3 O 4
D C5H4O3C 5 H 4 O 3
Question 2

This is another type of model: it is called a Lewis dot model or Lewis dot structure. The Lewis dot model represents carbon dioxide. What information is NOT provided by this model?
Responses
A The molecular formula, CO2.The molecular formula, CO 2 .
B The atomic number of each element in the compound.The atomic number of each element in the compound.
C The arrangement of the atoms of each element in the compound.The arrangement of the atoms of each element in the compound.
D The fact that there are double covalent bonds between the carbon and the two oxygen atoms.The fact that there are double covalent bonds between the carbon and the two oxygen atoms.

Answer 1

For Question 1, without seeing the ball and stick model, I can't determine the correct molecular formula based on the provided options and the color coding for carbon, oxygen, and hydrogen. However, I can help you with the methodology to determine the molecular formula based on the number of atoms represented by each color in the model. Count how many black (carbon), red (oxygen), and blue (hydrogen) balls there are in the model, and then match it to one of the provided options.

For Question 2, the Lewis dot structure for carbon dioxide (CO2) typically provides the following information:

• A) The molecular formula (CO2) is explicitly provided.
• B) The atomic number of each element is not shown in the Lewis dot structure. This information is not visualized but can be inferred from the periodic table.
• C) The arrangement of the atoms in the compound is indicated (central carbon with two oxygens bonded).
• D) The presence of double covalent bonds between the carbon and the two oxygen atoms is represented in the Lewis structure.

The correct answer for what information is NOT provided by the Lewis dot model is: B) The atomic number of each element in the compound.
