Chapter 1, Problem 20E

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).
