WebNov 9, 2015 · Joules to kJ/mol conversion. In my AP Chem class we are working on testing Hess's Law and conducted three reactions. Then enthalpy changes of the 1) N a O H + H C l and 2) N a O H + N H X 4 C l to predict the enthalpy change of 3) H C l + N H X 3. I used the equation q = C p m Δ T. We determined the q -values using a method given to us by our ... WebThe enthalpy of fusion of bromine is 10.57 kJ/mol and the enthalpy of vaporization of bromine is 29.96 kJ/mol. The specific heat of liquid bromine is 0.474 J/g⋅K. How much heat, in kJ, is required to convert 25.0 g of solid bromine at −7.25 °C to the gas phase at 58.8 °C? Solution: 1) Three calculations are needed: 1) melt solid bromine at −7.25

Joules to kJ/mol conversion - Chemistry Stack Exchange
WebValues are usually quoted in J/mol, or kJ/mol (molar enthalpy of vaporization), although kJ/kg, or J/g (specific heat of vaporization), and older units like kcal/mol, cal/g and Btu/lb are sometimes still used among others. Enthalpy of condensation[edit] WebThus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol. For example, consider the thermochemical equation. H 2 (g) + Cl 2 H = −184.6 kJ. The equivalences for this thermochemical equation are. 1 mol H 2 ⇔ 1 mol Cl 2 ⇔ 2 mol HCl ⇔ −184.6 kJ WebUse this calculator to determine the heat capacity in joules per kelvin (J/K), joules per degree Celsius (J/°C), kilojoules per kelvin (kJ/K), kilojoules per degree Celsius (kJ/°C), … cuisinart bread maker model cbk-110p1
