I do not understand any of this, please help.
1S. Estimate the enthalpy change for the reaction below from the average bond energies given. There are two CI-Cl and two C-H bonds in CHClh. Remember that energy is absorbed when boeds are broken and released when they are formed CF14(g) + 2C12(g) â CihCI(g) + 2HCI(g) Average Bond Energies C-H H-CI 413 kJ/mol 432 kJ/mol CI-CI242 kJ/mol C-CI 339 kJ/mol 16. If 4.168 kJ of heat is added to a calorimeter containing 75.40 g of water, the temperature of the water and the calorimeter increases from 24.58°C to 35.82°C. Caleulate the beat capacity of the calorimeter (in JPC). The specific heat of water is 4.184 J/g °C Calculate Î" at 25°C for the reaction below. 17, 3O2(g) 2ZnO(s) -348.3 2SOtg) -296.8 2ZnS(s) + â + Ar/mo -205.6 18. Given the enthalpy changes for the following reactions, calculate AH?, for CO(g). Arf -393.5 k C (graphite) + O2(g) â CO2(g) cog) + I/20, â CO2(g) AHo -283.0 kJ A 50.0 mL solution of 1.2 MHCI at 24.1â is mixed with 50.0 mL of 1.3 M NaOH, also at 241°C, in a coffee-cup calorimeter. After the reaction occurs, the temperature of the resulting mixture is 29.8°C.The density of the final solution is 1.05 gmL. Calculate the molar heat of neutralization. Assume the specific heat of the solution is 4.184 J/gs°C. The heat capacity of the calorimeter is 32.5 J°C f ZnS at constant pressure gives off 220. kJ of heat. Calculate the AH for this reaction 2ZnS(s) + 300-2ZnO(s) + 2SO2(g)
