How much work must be done to bring ion A and ion B together into an activated complex. The charge of ion A is +2 and it's ionic radius is 2.85 A and if the charge on ion B is +1 and it's ionic radius is 1.35 A. The ions were dissolved in a solvent with a dielectric constant of 18.59. Will this reaction be spontaneous? Why
Using a Sample of 0.3991 grams of an unknown monoprotic acid, HA, which combines with Sodium hydroxide according to the balanced equation HA + NaOH ® NaA + H2O when 35.30 mL of 0.1086 M Sodium hydroxide is required to titrate the acid to the equiv..
that the reaction was endothermic. If the enthalpy of reaction is negative, then we say that energy was released or that the reaction was exothermic. Most chemical reactions are exothermic.
A block of metal has a width of 3.2 rm cm, a length of 17.1 rm cm, and height of 4.5 cm. Its mass is 1.5 kg. Calculate the density of the metal.
