What's the chemical make up of methane and other compounds (listed inside)?

I need to know the make up of Methane, Ethane, Ethanol and Ammonia (ex: Lithium Sulfide is L(2)S).


I should know these, but about two weeks into school my class was changed, so I'm in a different class with a different teacher, and only got my actual textbook yesterday (because I had to look for some old textbooks from last year). My old teacher told me that the table telling me the information for the above was...somewhere, I don't remember where, and I never did get to even see it. This new teacher told everyone in their note taking before I got there, and now he expects me to -know- it, without even ever seeing it before. A little distressing, but I know I won't be getting any answers out of him. Any help at all would be much appreciated; I really need those formulas... Thanks.What's the chemical make up of methane and other compounds (listed inside)?
Methane CH4


Ethane C2H6


Ethanol C2H6O2


Ammonia NH3What's the chemical make up of methane and other compounds (listed inside)?
';METHANE is a chemical compound with the molecular formula CH4. It is the simplest alkane, and the principal component of natural gas. Methane's bond angles are 109.5 degrees. Burning one molecule of methane in the presence of oxygen releases one molecule of CO2 (carbon dioxide) and two molecules of H2O:


CH4 + 2O2 鈫?CO2 + 2H2O





ETHANE is a chemical compound with chemical formula C2H6. It is the only two-carbon alkane, that is, an aliphatic hydrocarbon. At standard temperature and pressure, ethane is a colorless, odorless gas.





ETHANOL, also known as ethyl alcohol, drinking alcohol or grain alcohol, is a flammable, colorless, slightly toxic chemical compound, and is best known as the alcohol found in alcoholic beverages. In common usage, it is often referred to simply as alcohol. Its molecular formula is variously represented as EtOH, CH3CH2OH, C2H5OH or as its empirical formula C2H6O. Based on its abilities to change the human consciousness, alcohol is considered a drug.





AMMONIA is a compound with the formula NH3. It is normally encountered as a gas with a characteristic pungent odor. Although ammonia contributes significantly to the nutritional needs of the planet, the gas itself is caustic and can cause serious health damage. The United States Occupational Safety and Health Administration (OSHA) has set a 15-minute exposure limit for gaseous ammonia of 35 ppm by volume in the environmental air and an 8-hour exposure limit of 25 ppm by volume.[5] Exposure to very high concentrations of gaseous ammonia can result in lung damage and death.[5] Although ammonia is regulated in the United States as a non-flammable gas, it still meets the definition of a material that is toxic by inhalation and requires a hazardous safety permit when transported in quantities greater than 13,248 L (3,500 gallons).[6]





Ammonia used commercially is usually named anhydrous ammonia. This term emphasizes the absence of water. Because NH3 boils at -33 掳C, the liquid must be stored under pressure or at low temperature. Its heat of vaporization is, however, sufficiently high that NH3 can be readily handled in ordinary beakers in a fume hood. ';Household ammonia'; or ';ammonium hydroxide'; is a solution of NH3 in water. The strength of such solutions is measured in units of baume (density), with 26 degrees baume (about 30 weight percent ammonia at 15.5 掳C) being the typical high concentration commercial product.[7] Household ammonia ranges in concentration from 5 to 10 weight percent ammonia.';
