- Insoluble AgCl(s) precipitates when solutions of AgNO3(aq) and NaCl(aq) are mixed. AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) rH = ? To measure the energy evolved in this reaction, 250. mL of 0.16 M AgNO3(aq) and 125 mL of 0.32 M NaCl(aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises from 21.15 C to 22.90 C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol. (Assume the density of the solution is 1.0 g/mL and its specific heat capacity is 4.2 J/g K.)arrow_forwardThe equation for the combustion of 2 mol of butane can be written 2C4H10(g)+O2(g)8CO2(g)+10H2O(g);HO Which of the following produces the least heat? a Burning 1 mol of butane. b Reacting 1 mol of oxygen with excess butane. c Burning enough butane to produce 1 mol of carbon dioxide. d Burning enough butane to produce 1 mol of water. e All of the above reactions (a, b, c, and d) produce the same amount of heat.arrow_forwardHow much heat, in kilojoules, must be removed to decrease the temperature of a 20.0-g bar of aluminum from 34.2 C to 22.5 C?
