Specific Expectations
D1.1 analyse some conventional and alternative energy technologies (e.g., fossil fuel–burning power plants, hydro-powered generators, solar panels, wind turbines, fuel cells), and evaluate them in terms of their efficiency and impact on the environment.
D2.1 use appropriate terminology related to energy changes and rates of reaction, including, but not limited to: enthalpy, activation energy, endothermic, exothermic, potential energy, and specific heat capacity
D2.2 write thermochemical equations, expressing the energy change as a ΔH value or as a heat term in the equation
D2.3 solve problems involving analysis of heat transfer in a chemical reaction, using the equation Q = mcΔT (e.g., calculate the energy released in the combustion of an organic compound, and express the results in energy per mole of fuel [J/mol])
D2.4 plan and conduct an inquiry to calculate, using a calorimeter, the heat of reaction of a substance (e.g., the heat of solution of ammonium nitrate, or of combustion of a hydrocarbon), compare the actual heat of reaction to the theoretical value, and suggest sources of experimental error
D2.5 solve problems related to energy changes in a chemical reaction, using Hess’s law
D2.7 calculate the heat of reaction for a formation reaction, using a table of standard enthalpies of formation and applying Hess’s law
D3.1 compare the energy changes resulting from physical change (e.g., boiling water), chemical reactions (e.g., bleaching a stain), and nuclear reactions (e.g., fission, fusion), in terms of whether energy is released or absorbed
