Chapter 1, Problem 22E
A chemist decomposes several samples of water into hydrogen and oxygen and measures the mass of the hydrogen and the oxygen obtained. The results are tabulated as follows.
| Sample Number | Grams of Hydrogen | Grams of Oxygen |
| 1 | 1.5 | 12 |
| 2 | 2 | 16 |
| 3 | 2.5 | 20 |
a. Summarize these observations in a short statement.
Next, the chemist decomposes several samples of carbon dioxide into carbon and oxygen. The results are tabulated as follows:
| Sample Number | Grams of Hydrogen | Grams of Oxygen |
| 1 | 0.5 | 1.3 |
| 2 | 1.0 | 2.7 |
| 3 | 1.5 | 4.0 |
b. Summarize these observations in a short statement.
c. Formulate a law from the observations in (a) and (b).
d. Formulate a theory that might explain your law in (c).
