WebCH4 (g)→C (g)+4H (g) 714 + (4x217.94) + 74.8 = 1660.56 kJ ANSWER: 1660.6 kJ Calculate the enthalpy change, ∘ΔH, for the reverse of the formation of methane: CH4 (g)→C (s)+2H2 (g) 74.8 kJ The air in an inflated balloon (defined as the system) is warmed over a toaster and absorbs 130 J of heat. As it expands, it does 78 kJ of work. WebVandaag · CH4 (methane) is a tetrahedral compound with four C-H bonds, and at room pressure and temperature, it is an odorless, colorless, and easily flammable gas. It was discovered and isolated by a scientist named Alessandro Volta when he was studying marsh gas around 1776. upcoming bay area concerts
What hydrocarbon does the formula CH4 represent? - Answers
Web28 feb. 2015 · A certain saturated hydrocarbon effuses about half as fast as methane, #CH_4#. What is the molar mass, in g/mol, of this hydrocarbon ? Chemistry. 1 Answer ... Impact of this question. 3295 views around the world ... WebCH 4 Molecular Geometry And Bond Angles We have already discussed the bond formation and hybridization process above. Determining CH 4 molecular geometry should be easier. In methane, the four hybrid orbitals are located in such a manner so as to decrease the force of repulsion between them. WebAnswer (1 of 4): Hydrocarbons are compounds that contain only the elements carbon and hydrogen. A molecule of methane contains only one carbon atom and four hydrogen atoms. Hence, methane is a hydrocarbon. upcoming best games
