The chemical reaction shown below is carried out in a coffee cup calorimeter . A student mixes 10.0 mL of 0.100 M H 2 A(aq) and 20 mL of 0.100 MNaOH * (aq) , both initially at 25°C. The student records the highest temperature of 40.C for the reaction . H 2 A(aq)+2NaOH(aq) Na 2 A(aq)+2H 2 O(l) AH = ??? KJ/molx a. What indicates that this is an acid -base reaction ? Explain your answer . B. Determine the amount of energy involved in the reaction in the coffee cup calorimeter . The density of the resulting solution is 1.00g / m * L and has the same specific heat capacity as water , 4.2 J/ g °C c. Determine the enthalpy of the reaction , in kJ/mol r* n

your answers are a,b,,e and f

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.
