The Federal Communications Commission (FCC) is an independent agency of the United States government, created by Congressional statute (see 47 U.S.C. Â§ 151 and 47 U.S.C. Â§ 154) to regulate interstate communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories.
Water consists of H2O molecules that each conprise 3 atoms. A typical H2O molecule as a molecular weight of 18, disregarding isotopes. That means one mole weighs 18 grams. 1000 g / 18 g = 55.6 mole H2O in a liter of water. One mole is around 6 x 10^23 so around 3 x 55.6 x 6 or 1000 mole atoms. Wolfram|Alpha confirms: how many atoms are in a liter of water.
Berkeley, creator of Physics for Future Preside... A molecule of methane consists of 4 hydrogen atoms and one carbon atom: C H4. Oxygen molecules are O2. To burn (combine) you need two O2 molecules. C H4 + 2 O2 --> CO2 + 2 H2O. The process gives off energy (that means that the outgoing molecules of carbon dioxide (CO2) and water (H2O) have high velocity and heat up the surroundings, perhaps triggering other methane and oxygen molecules to combine (that is, to burn).
