Question

how do carbon dioxide, water, glucose, and oxygen differ? select all that apply. the combination of atoms the arrangement of atoms the combination of bonds

Explanation:

To determine how carbon dioxide ($\ce{CO_2}$), water ($\ce{H_2O}$), glucose ($\ce{C_6H_{12}O_6}$), and oxygen ($\ce{O_2}$) differ:

• Combination of atoms: $\ce{CO_2}$ has C and O; $\ce{H_2O}$ has H and O; $\ce{C_6H_{12}O_6}$ has C, H, O; $\ce{O_2}$ has only O. Their atom combinations differ.
• Arrangement of atoms: Even if two molecules have the same atoms (e.g., isomers), arrangement matters. Here, each molecule (e.g., $\ce{CO_2}$ is linear, $\ce{H_2O}$ is bent) has a unique atom arrangement.
• Combination of bonds: $\ce{CO_2}$ has double bonds, $\ce{H_2O}$ has single bonds, $\ce{C_6H_{12}O_6}$ has single and some double bonds, $\ce{O_2}$ has a double bond (but the overall bond “combination” across molecules differs in type and number).

Answer:

A. the combination of atoms
B. the arrangement of atoms
C. the combination of bonds

(Note: All three options are correct as explained above.)
