Consider the substances in Table 9.3. Which substance requires the largest amount of energy to raise the temperature of 25.0 g of the substance from 15.0oC to 37.0oC? Calculate the energy. Which substance in Table has the largest temperature change when 550 g of the substance absorbs 10.7 kJ of energy? Calculate the temperature change.
Answer to relevant QuestionsA 150.0-g sample of a metal at 75.0oC is added to 150.0 g of H2O at 15.0oC. The temperature of the water rises to 18.3oC. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is ...In a coffee cup calorimeter, 50.0 mL of 0.100 M AgNO3 and 50.0 mL of 0.100 M HCl are mixed. The following reaction occurs: Ag+(aq) + Cl2(aq) → AgCl(s) Given the following data: Calculate ΔH for the reaction On the basis of enthalpy change, is this a useful reaction for the synthesis of ammonia? Given the following data: 2O3(g) → 3O2(g) ΔH = –427 kJ O2(g) → 2O(g) ΔH = 495 kJ NO(g) + O3(g) → NO2(g) + O2(g) ΔH = –199 kJ Calculate ΔH for the reaction NO(g) + O(g) → NO2(g) The reusable booster rockets of the space shuttle use a mixture of aluminum and ammonium perchlorate as fuel. A possible reaction is 3Al(s) + 3NH4ClO4(s) → Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O(g) Calculate ΔHo for this ...
