Define vapor pressure and give its explanation. Why is condensation exothermic? How is the heat of combustion related to hyperconjugation? Tell how a voltaic cell works. Be sure to mention the various parts of the voltaic cell and what they have to do with how it works. ...
Why do reactants become hotter during exothermic reactions when they are losing energy and why do reactants become colder when they are gaining energy in endothermic reactions? Why would Kepler's discovery of the ellipse as the preferre...
In the case of nuclear reactions, the Q value is simply the mass of the reactants minus the mass of the products (the reverse of most of chemistry). A positive Q value implies that the reaction is exothermic and that over time the reaction will tend towards the products. The reverse is...
Endothermic and exothermic reactions Potential energy diagrams Calorimetry, heat capacity, and specific heat Hess's Law Heat of formation/combustion Bond energies Labs Guided Inquiry Lab:Hess's Law Students perform a series of reactions and calculate enthalpy, proving Hess's law. ...
Is the Haber process endothermic or exothermic? How much pressure does it take to create metallic hydrogen? How does temperature affect the rate of a chemical reaction? The table below follows the decomposition of N 2 O 5 gas by examining the partial pressure of the gas as a f...
