20. A chemist decomposes several samples of water into hydro- gen 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 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 Carbon Grams of Oxygen 1 0.5 1.3 2 1.0 2.7 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).

Gaseous methane CH4 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O . Suppose 0.642 g of methane is mixed with 4.3 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to 3 significant digits.
Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. . Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. g of the powder is put into a funnel lined with a sheet of thick paper. Distilled water is poured slowly over the powder. All of the powder disappears, and the water under the funnel turns a deep purple. . Sample B is 100. mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77 g/mL. The liquid is then cooled in the refrigerator At 10.0 °C crystals begin to appear. The temperature of the liquid continues to decrease as more crystals form, until at 6.2 °C the liquid is entirely solid. Is sample A made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide." Is sample B made from a pure substance or a…
