While 5.00mL of a sodium nitrite solution containing 17.04 g/L of sodium nitrite is added to 25.00mL of sulfuric acid solution containing 2.754 g/L of sulfuric acid, the following reaction occurs
NaNO2 (aq) + HSO3NH2(aq) →N2(g) + H2O (l) + NaHSO4(aq)
a) Find out the mass of nitrogen gas produced and calculate the volume occupied by this mass of gas at temperature of 23*C and a pressure of 99.5 kPa.
b) While this experiment was conducted the nitrogen gas was collected over water, the volume of wet nitrogen produced at 23C and 99.5kPa was 14.81mL. Explain what the percentage yield was obtained by the student. The vapor pressure of the water at 23C is2.81 kPa
Draw a concentration cell for 0.10 M Cu2+ and 2.0 M Cu2+ cell, show the following on each compartment clearly. a) All the component of each cell, including the concentrations in anode and cathode half cells.
how does a large electronegativity difference affect molecular properties?1. it makes the bonds stronger and shorter
What pair of elements would you expect to exhibit the greatest similarity in physical and chemical properties. WHY.
Arsenic acid (H3AsO4) is a triprotic acid with Ka1 = 5. 10-3, Ka2 = 8. 10-8, and Ka3 = 6. 10-10. Calculate [H + ], [OH ? ], [H3AsO4], [H2AsO4? ], [HAsO42- ], and [AsO43- ] in a 0.23 M arsenic acid solution.
A catalyst decreases the activation energy of a particular exothermic reaction by 59 kJ/mol, to 51 kJ/mol. Assuming that the mechanism has only one step, and that the products are 94 kJ lower in energy than the reactants
