Chapter 2: Problem 94

Carbohydrates, a class of compounds containing the elements carbon, hydrogen, and oxygen, were originally thought to contain one water $\left(\mathrm{H}_{2} \mathrm{O}\right)$ molecule for each carbon atom present. The carbohydrate glucose contains six carbon atoms. Write a general formula showing the relative numbers of each type of atom present in glucose.

Short Answer

Expert verified
The general formula for glucose, based on the assumption that it contains one water molecule for each carbon atom present, is \(\text{C}_6\text{H}_{12}\text{O}_6\).

Step by step solution

01

Identify the number of carbon atoms in glucose

Glucose has six carbon atoms, which can be represented as C6.
02

Determine the number of water molecules

As mentioned, carbohydrates were thought to contain one water molecule (H2O) for each carbon atom present. Therefore, glucose must have six water molecules since there are six carbon atoms.
03

Determine the number of hydrogen and oxygen atoms

In each water molecule, there are two hydrogen atoms and one oxygen atom. With six water molecules, we will have: - Hydrogen atoms: 6 x 2 = 12 - Oxygen atoms: 6 x 1 = 6
04

Write the general formula for glucose

Combine the information from steps 1-3 to write the general formula for glucose. We have: - Carbon atoms: C6 - Hydrogen atoms: H12 - Oxygen atoms: O6 So, the general formula for glucose is \(\text{C}_6\text{H}_{12}\text{O}_6\).

For lighter, stable isotopes, the ratio of the mass number to the atomic number is close to a certain value. What is the value? What happens to the value of the mass number to atomic number ratio as stable isotopes become heavier?

Section 2.3 describes the postulates of Dalton’s atomic theory. With some modifications, these postulates hold up very well regarding how we view elements, compounds, and chemical reactions today. Answer the following questions concerning Dalton’s atomic theory and the modifications made today. a. The atom can be broken down into smaller parts. What are the smaller parts? b. How are atoms of hydrogen identical to each other, and how can they be different from each other? c. How are atoms of hydrogen different from atoms of helium? How can H atoms be similar to He atoms? d. How is water different from hydrogen peroxide $\left(\mathrm{H}_{2} \mathrm{O}_{2}\right)$even though both compounds are composed of only hydrogen and oxygen? e.
