Question

Consider the solubility of BaSo. If Ba(NO_3), is added to the solution, the solubility fo the barium sulfate: Hydrogen is produced industrially by reacting propane and liquid water: C_2 H_2(g) + 3 H_2O(l) rightarrow 3 CO(g) + 7 H_2(g) If the denominator of equilibrium expression is expressed as: [C_2H_2] [H_2O]^2, what are the values of "m" and "n"? In a dynamic equilibrium: The conjugate base of ammonium chloride is: The synthesis of the pesticide thionyl chloride (OSCl_2) proceeds according to: SO_1(g) + SCl_2(l) OSCl_2(l) + SO_2(g) If Delta G degree = - 106 kJ/mol for this reaction at 298K, what is the K_aq at this temperature? Recall: R = 8.314 J mol^-1 K^-1. What change in reaction direction occurs. If dilute HCl is added to H_2PO_4^- reduction? H_2PO_2^1- + H_2O HPO_2^2+ + H_2O^- What is the molar solubility of CaF_2 (K_aq = 3.9 Times 10^-11)? What is the pH of a 0.1055 M CH_2COOH solution (K_2 = 1.75 Times 10^-5)? What is the pH of a 0.150 N NaOH solution? Which of following species is a Bronsted-Lowry acid? A large "" value (>0) indicates that the reaction tends to favor the forward direction and the formation of products.
