N the following experiment, a coffee-cup calorimeter containing 100 mLmL of H2OH2O is used. The initial temperature of the calorimeter is 23.0 ∘C∘C. If 3.70 gg of CaCl2CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter? The heat of solution ΔHsolnΔHsoln of CaCl2CaCl2 is −82.8 kJ/mol−82.8 kJ/mol. Assume that the specific heat of the solution formed in the calorimeter is the same as that for pure water: Cs=4.184Cs=4.184 J/g⋅∘CJ/g⋅∘C.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
