A student dissolves 13.8 g of potassium hydroxide KOHin 200. g of water in a well-insulated open cup. She then observes the temperature of the water rise from 22.0 °C to 37.3 °C over the course of 6.1 minute Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: 1 KOH(s) - K (aq) + OH (aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 3 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. O exothermic endothermic X 5 ? Is this reaction exothermic, endothermic, or neither? neither If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. Calculate the reaction enthalpy AH per mole of KOH.

it is the most commonly accepted one

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
