Methyl salicylate + NaOH --> disodium salicylate + Ch3OH + H20 disodium salicylate + H2SO4 --> salicylic acid + Na2SO4 The two chemical equations above are for the synthesis of salicylic acid. In the second equation, when H2SO4 is added quickly to disodium salicylate, smokes appear as a result of a fast exothermic reaction. Does some of the disodium salicylate evaporate?
At what total pressure of bismuth vapor is the partial pressure of Bi(g) just twice that of Bi2(g) at 1000 K? How many phases are present in the system for this situation?
Water has a heat opf vaporization of 40.7 kJ/mol and a specific heat of 4.18 J/grams degrees celsius. How many Joules of heat are required to boil a cup of tea?
Under What circumstances is it possible for the requirements for chirality at a carbon atom to be satisfied but for a molecule containing
Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below. HCl is a stronger acid than H2S because Cl is more electronegative than S.
Provide a structure for the following compound: EI mass spectrum: two molecular ions of about equal intensity at m/z = 180 and 182; IR: 1740 cm-1; 1H NMR
A reaction was conducted in benzene as the solvent. Because the reaction was very exothermic, the mixture was cooled in a salt-ice bath. This was a bad choice. Why?
Calculate the number of moles of CO 2
Assuming that the deformation is completely elastic, compute the amount of stress that is put on the nickel 200 alloy. Use values of Yield Stress, Ultimate Tensile Strength, Coefficient of Thermal Expansion and E for nickel 200 alloy.
