CHEM 1210 Study Guide - Quiz Guide: Rubidium Hydroxide, Barium Hydroxide, Calcium Hydroxide
Document Summary
The oxidation number of oxygen in a peroxide ion. The oxidation number of hydrogen when bonded to a metal. The oxidation number of hydrogen when bonded to a nonmetal. The total energy of the universe is a constant; if the system loses energy, it must be gained by the surrounding, and vice versa. Internal energy delta e = efinal - einitial. If a reaction is carried out in a series of steps, delta h for the overall reaction will be equal to the sum of the enthalpy changes for the individual steps. The enthalpy change for the reaction in which 1 mole of substance is formed from its constituent elements in their elemental forms. Ozone in the upper atmosphere absorbs energy in the 210-230 nm range of the spectrum. The energy absorbed by ozone falls in the 210-230 nm range. Ex: pot of boiling water on a stove) closed systems systems that exchange energy but not matter with their surroundings.
