14 Show the product of the following transformation. Follow the mechanism, if you need to to figure it out. cat. H2SO/dioxane remove water ?? ?? 15 When dimethyl acetals are made from aldehydes or ketones, water is often distilled as an azeotrope from the reaction to drive the acetal formation to completion. When this isn't possible, trimethylorthoformate (an ortho ester)...
Metallic copper does not react with hydrochloric acid, but is oxidized by nitric acid since the nitrate ion functions as the oxidizing agent in acidic solutions. lf NO and Cu^2+ are formed as products, and the reaction is carried out under standard conditions, E^0 for the reaction of copper metal with nitric acid will be: +0.44 V +0.62 V +0.78...

Calculate the equilibrium constant K and the standard free energy change ΔrG˚ at room temperature for the following reaction, HF(aq) H+(aq) + F- (aq) At equilibrium, you measured the following concentrations of reactants and products: [HF]eq = 0.092 M, [H+] eq = 0.008M, [F- ] eq = 0.008 M Think about it: According to your calculation of ΔrG˚, is...
The reaction N2(g) + O2(g) ⇄ 2 NO(g) contributes to air pollution whenever a fuel is burned in air at a high temperature, as in a gasoline engine. At 1500 K, Kc = 1.0×10-3. Suppose a sample of air has [N2] = 0.70 mol/L and [O2] = 0.20 mol/L before any reaction occurs. Calculate the equilibrium concentrations of reactants and...
In a calorimetry experiment, the following reaction was studied: 2NaOH(aq) + H2SO4(aq) Na2SO4(aq) + 2H2O(l) 100.0 mL portions of 1.00 M NaOH and H2SO4, at 24°C, were mixed. The maximum temperature achieved was 30.6°C. Neglecting the heat capacity of the coffee–cup calorimeter, and assuming that the products has a density of 1.0 g/mL and a heat capacity of 4.184...
