Question 6 options: Reaction with (1) H2SO4 (cat.), H2O, followed by (2) NaCN Reaction with (1) HBr/ROOR, followed by (2) NaCN Reaction with (1) HBr, followed by (2) NaCN Reaction with (1) Br2 in H2O, followed by (2) NaCN
When a sample of 5.00-g rams of Potassium thiocyanate is dissolved in H2O in a calorimeter that has a total heat capacity =6.225 kJ•K-1, the temperature decreases by 0.200 Kelvin. compute the molar heat of solution of Potassium thiocyanate.
(A) What is the electron configuration of diatomic BN+? What is its bond order?
If 60mL of 0.1M CH3COOH is titrated with 0.2M NaOh, what will the pH be when: 1. Initial, before adding NaOH 2. 15mL of NaOH is added 3. 30mL of NaOH is added I worked the pH levels to 2.87, 4.74, and 10.21 (none, 15mL, 30mL NaOH).
A solution of .601g of the solid in 34.1g of the solvent diphenyl gave a freezing point depression of 1.17 degree celsius. Calculate the molar mass and molecular formula of the solid(k1 for diphenyl is 8.00 degree celsius/m)
How much heat in Joules was lost by the water. How much heat would be lost by the water if 1 mole of KCl had dissolved. c) What is (Delta Heat reaction) in kL/mole for this process, which can be written as KCl (s) --> KCL (aq)
