Chem 106 Exam 5 Questions And Correct Answers

Active Metal - Correct Answer a metal that reacts with water at room temperature Coulomb - Correct Answer SI unit of electric charge first law of thermodynamics - Correct Answer Energy cannot be created or destroyed. It can only change form. Non Spontaneous - Correct Answer Needs push from outside source, uphill, consumes energy from surroundings Spontaneous - Correct Answer does not need energy from an outside source, downhill, supplies ev=nergy to surroundings Ampere - Correct Answer unit of electric current Enthalpy (H) - Correct Answer total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume. Free energy (G) - Correct Answer energy released that is available to do work Reducing Agent - Correct Answer The electron donor in a redox reaction. Standard State (º) - Correct Answer the reference state for the material's thermodynamic state properties Anode - Correct Answer Positive electrode Entropy (S) - Correct Answer measure of randomness or disorder within a system Galvanic Cell - Correct Answer The downhill transfer of free energy from a spontaneous redox reaction into voltage Salt-Bridge - Correct Answer A tube that allows the slow transfer of ions and maintains the neutrality of the electrolyte solutions.
