Energetics 5.1 5.1.1 Endothermic: A reaction in which energy is absorbed. If your reactants are at a lower energy level than your products then the reaction is endothermic this means it has a + ΔH° Exothermic: A reaction in which energy is released. If your reactants are at a higher energy level than your products then the reaction is exothermic this means it has a ΔH° Standard Enthalpy ( ΔH°) The internal energy stored in the reactants. Only changes in enthalpy can be measured

Lacsap’s Fractions IB Math SL SL Type 1 December 11‚ 2012 Lacsap’s Fractions: Lacsap is Pascal backwards and the way that Lacsap’s fractions are presented is fairly similar to Pascal’s triangle. Thus‚ various aspects of Pascal’s triangle can be applied in Lacsap’s fraction. To determine the numerators: To determine the numerator (n)‚ consider it in relation to the number of the row (r) that it is a part of. Consider the five rows below: Row 1
