How much heat (in kJ) will be released (AH) if 0.4501 mol of NH3 are mixed with 0.200 mol of O, in the following chemical reaction? 4 NH3 (g) + O2 (g) → 2 N‚H4 (g) + 2 H,O (g) AH° = -286 kJ/mol
An ideal gas in a cylinder fitted with a piston expands at constant temperature from a pressure of 9 atm and a volume of 4.,0 L to a final volume of 13 L against a constant opposing pressure of 1.4 atm. How much heat does the gas absorb, expressed in units of L atm (liter x atm)? Latm
To measure the enthalpy of an acid-base reaction, a student places the thermometer in the hydrochloric acid solution, and then, without rinsing with DI water, places it in the sodium hydroxide solution prior to adding the hydrochloric acid solution to the calorimeter. How would this affect the calculated enthalpy of the reaction, be too high, too low, or unaffected? Why?

A 5.43 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C. If -3.13 x 10 J of heat was lost during the dissolution reaction of 0.0465 moles of the unknown salt, what is the enthalpy change (in kJ/mol of salt) for the dissolution reaction? Type here to search
50.0mL of a solution of HCl is combined with 100.0mL of 1.15 M NaOH in a calorimeter. The reaction mixture is initially at 22.4 degrees C and the final temperature after reaction is 31.2 degrees C. What is the molarity of the HCl solution? ( Assume that there is an excess of base (so all of the HCl has reacted), that the specific heat of the reaction mixture is 0.96 cal/g degrees C, and that the density of the reaction mixture is 1.02 g/mL. The heat of neutralization of HCl and NaOH is 13.6 kcal/mol.)
