Explanation Given: [H 2 S] =0.500 M; [SO 2 ] = 0.500 M; [H 2 O] = 0.0011 [H 2 S]=0.250 M; [SO 2 ] = 0.325 M Formula used: K = [H2O ] 2 [ H2S] 2 [SO2] Calculation: First, we must find the equilibrium constant given the initial concentrations: K = ( 0.0011 ) 2 ( 0.500 ) 2 ( 0.500 ) = 9.68 × 10 − 6 Now, that we have the equilibrium constant, we can enter the values into the ICE table to find the expressions for the equilibrium concentrations: H 2 S SO 2 H 2 O I 0.250 0.325 0 C -2 x - x +2 x E 0.250 – 2 x 0.325 – x 2 x We can insert these values into the equilibrium expression to solve for x : 9.68 × 10 − 6 = [ 2 x ] 2 [ 0...

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol. Which experimental number must be initialled by the Lab TA for the first run of Part 1 of the experiment? a) the heat capacity of the calorimeter b) Mass of sample c) Ti d) The molarity of the HCl e) Tf
