E. ANS: B PTS:1 OBJ:6. In the chapter that follows, we will study energy changes at the molecular level and the consequences those energy changes have on the properties of atoms and elements. 2 2 Δ= H m Required:; . We are able to rearrange two chemical equations and add their enthalpy change values to determine the enthalpy change of a third reaction because of Hess’s law. Ø Heat: Energy used to cause the temperature of an object to rise. 3: Enthalpy; 5. A measure of the heat energy that is released or absorbed when bonds are broken and formed during a reaction that is run at CONSTANT PRESSURE. 11 x 10^-28 g.
