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.

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
