#C1.2.1
distinguish between endothermic and exothermic reactions on the basis of the temperature change of the surroundings
#C1.2.2
draw and label a reaction profile for an exothermic and an endothermic reaction, identifying activation energy
#C1.2.3
explain activation energy as the energy needed for a reaction to occur
#C1.2.4
interpret charts and graphs when dealing with reaction profiles
#C1.2.5
calculate energy changes in a chemical reaction by considering bond breaking and bond making energies
#C1.2.6
carry out arithmetic computations when calculating energy changes
#C1.2.7
describe how you would investigate a chemical reaction to determine whether it is endothermic or exothermic
#C1.2.8
recall that a chemical cell produces a potential difference until the reactants are used up
#C1.2.9
evaluate the advantages and disadvantages of hydrogen/oxygen and other fuel cells for given uses
