Hydrogen cyanide is used in the manufacture of clear plastic such as plexiglas. it is prepared from ammonia and methane according to the following reaction. calculate the value of q(KJ) if 9.436 g of ammonia react with excess oxygen and methane.
When chemical A and chemical B are mixed together, and endothermic reaction below occurs:4A(aq) + 3B(s) --> 2C(aq)To find the enthalpy of this reaction, a scientist pours 155 mL of a 0.33 M solution A into abeaker and measures the temperature to be 20.1 ̊C. To this same beaker the scientist thenadds 3.75 g of substance B with stirring (molar mass of B is 33 g/mol), and finds thetemperature to now be 16.3 ̊C. Calculate the molar enthalpy of this reaction for every mole ofC produced.
Nitric acid, HNO3, reacts with potassium hydroxide as follows: HNO3(aq) + KOH(aq) ⟹ KNO3(aq) + H2O(l) A student places 55.0mL of 1.3M HNO3 in a coffee cup calorimeter, and noted that the temperature was 23.5oC. 55mL of 1.3M KOH also at 23.5oC was added. After quickly stirring with a thermometer, the temperature rose to 31.8oC. Calculate the heat generated by the reaction.
When 130. mL of 0.198 M NaCl(aq) and 130. mL of 0.198 M AgNO3(aq), both at 21.8°C, are mixed in a coffee cup calorimeter, the temperature of the mixture increases to 24.2°C as solid AgCl forms. NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) This precipitation reaction produces 2.60 ✕ 103 J of heat, assuming no heat is absorbed by the calorimeter, no heat is exchanged between the calorimeter and its surroundings, and that the specific heat and density of the solutions are the same as those for water (4.18 J/g·°C, and 0.997 g/mL, respectively). Using this data, calculate ΔH in kJ/mol of AgNO3(aq) for the given reaction. This is the complete question, nothing was left out. Thank you
