Question

its time for the unit exam. this is your opportunity to show how much you have gained from all the if you dont feel ready, you may want to stop and clarify anything you do not understand. it may also over any notes you have taken and review the key terms. good luck! note: to answer some of the questions, it may help to reference a periodic table. what is the difference between a molecular formula and a structural formula? a molecular formula will show the smallest whole - number ratio for the different atoms in a compound, while the structural formula will show the actual number of atoms in a molecule. a molecular formula will show the actual number of atoms in a molecule, while the structural formula will show the organization and layout of the atoms in the compound. a molecular formula will show the smallest whole - number ratio for the different atoms in a compound, while the structural formula will show the organization and layout of the atoms in a compound. a molecular formula will show the organization and layout of the atoms in the compound, while the structural formula will show the actual number of atoms in a molecule.

Explanation:

A molecular formula shows the actual number of atoms in a molecule (e.g., for glucose \(C_6H_{12}O_6\), it shows 6 carbon, 12 hydrogen, and 6 oxygen atoms). A structural formula shows how the atoms are organized and laid - out in the compound (e.g., it would show the bonds between carbon, hydrogen, and oxygen atoms in glucose). The first option wrongly swaps the definitions. The third option wrongly describes the molecular formula as showing the smallest whole - number ratio (that's the empirical formula). The fourth option also has the definitions swapped.

Answer:

A molecular formula will show the actual number of atoms in a molecule, while the structural formula will show the organization and layout of the atoms in the compound.
