Document Summary

Final study guide: known as the father of modern chemistry, when you burn a wooden log, all that remains is a small amount of ash. Energy in chemical changes: endothermic a change in which energy is transferred from the surroundings to the system (heat in the reactants) Exothermic a reaction that results in the transfer of energy to its surrounding (heat in the product) Law of conservation of mass the total mass of reactants in a chemical change is equal to the total mass of the products. Law of conservation of energy the quantity of energy within an isolation system does not change, energy in a system must remain constant. Scientific notation: expressing very small and very large numbers. Temperature-converting temperature from celsius to fahrenheit and to kelvin. Law of definite composition any compound is always made up of elements in the same proportion by mass.
