Introduction Enthalpy change‚ ΔH‚ is defined as the heat output of a system as it goes through a reaction under constant pressure. It is an important aspect of thermochemistry‚ which is the study of energy changes during a chemical or physical reaction . When we calculate enthalpy change‚ we always assume that the pressure is constant. We are able to calculate enthalpy change numerous ways‚ notably by the increase in heat‚ Q‚ given by an exothermic reaction or the heat absorbed by an endothermic

Chapter 5 Notes The study of energy and its transformations is called thermodynamics. An aspect of thermodynamics that deals with the relationships between chemical reactions and energy changes involving heat is called thermochemistry. 5.1 The Nature of Energy Energy is defined as the capacity to do work or produce heat. Work is the energy used to cause an object with mass to move. Heat is the energy of an object that causes its temperature to increase. Kinetic and Potential Energy

Moles 1.How is molar mass calculated and why is it useful? You have to multiply the atomic weight of each element by the number of atoms that it contains in a compound. Molar mass is useful because its used to change a measurement of mass to an amount of a substance such as the number of particles. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. A mole measures the amount of a substance. Three examples that are equivalent to a mole is molar
