Methanol (CH3OH) can be made by controlled oxidation of methane. CH4(g) 1/2 O2(g) ? CH3OH(g) (a) Calculate ?H° and ?S° for this reaction. (b) Calculate ?G° at 298 K. (c) Calculate the temperature at equilibrium.
The standard deviation of the analytical method was determined to be +/-2.3%. What is the standard deviation overall? And in order to reduce the overall standard deviation to +/- 5.0%
What is the system? What is the surrounding? In what direction does the heat flow? Is the process endothermic or exothermic?
Other than S=C=S; can I have S triple bonded to C single bonded to S? Wouldn't there be three electrons left on the triple bonded S; it would be sharing three when it started with six I don't understand? Help please.
