CHEM 121 FINAL EXAM | UPDATED QUESTIONS AND ANSWERS UPDATED .Buy Quality Materials! thermodynamics the study of energy, work, and heat (applied to chemical and physical changes, explain why some chemical reactions do or don't occur) thermochemistry relationships between chemical reactions and energy changes involving heat energy capacity to do work or produce heat, needed to oppose natural attractions law of conservation of energy energy can be converted from one form to another but...

CHEM 101L- EXP. 6 QUESTIONS AND ANSWERS Experiment 6 In this lab, the temperature of three different reactions will be recorded and graphed. The graph will be used to extrapolate the maximum temperature of those reactions , and those temperatures will in turn be used to calculate their enthalpy change. Enthalpy is the total heat content of a system. Negative enthalpy changes indicate an exothermic reaction, as the heat content of the system escapes to its surroundings. Positive enthalpy c...

Chemical Hand Warmers - ANSWER-Most hand warmers work by using the heat released from the slow oxidation of iron 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) The amount your hand temperature rises depends on several factors: The size of the hand warmer The size of your glove, etc. Mainly, the amount of heat released by the reaction. Nature of Energy - ANSWER-Even though chemistry is the study of matter, energy affects matter Energy - ANSWER-is anything that has the capacity to do work Energy c...
