A 27 g sample of ammonium carbamate (NH4(NH2CO2)), was placed in an evacuated 0.25 L flask and kept at 25?C. At equilibrium, 16.4 mg of CO2 was present.NH4(NH2CO2)(s) ?? 2 NH3(g) + CO2(g) .What is the value of Kc for the decomposi- tion of ammonium carbamate into ammonia and carbon dioxide?
what are the pH and the change in pH after the addition of 0.054 mol hydrochloric acid to the buffer solution?
Explain why a 1m solution of the compound FeCl2 in water has a lower freezing temperature than a 1m solution of KCl in water and what is the empirical formula
Write a balanced molecular equation for these ten combinations.
Order of a reaction, Consider a kinetic study of oxidation of a new plastic stabiliser being proposed for the automobile industry. Stabiliser + H+ + O2 ----> Byproduct
Calculate molarity?if one mole of sodium hydroxide was dissolved estimate the number of calories that would be produced. (ΔHsolnNaOH)
A solution is prepared by mixing 79.0 mL of 5.00 M HCl and 34.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
At 25 0C the density of a 50 % (by mass) ethanol/water solution is 0.914 g/cc. Given that the partial molar volume of water in the solution is 17.4 cc/mol.
What is the molarity of a HCl solution if the reaction of 200 mL of the HCl solution with excess CaCO3 produces 14.0 L of CO2 gas at 725 mmHg at 18 degree celsius.
When 0.100g of graphite is burned completely in a bomb calorimeter(heat capacity =3.344kJ/?C), containing 3000 g of water, a temperature rise of 0.21?C is observed.
A solution is made by mixing 506 mL of water and 198 mL ethanol. What is the concentration of ethanol in units of volume/volume percent.
Draw the Lewis structure of the conjugate base for the following acid: H2SO4. Remember to include charges and non-bonding electrons where necessary. Use an expanded octet on sulfur to minimize formal charges.
