I have those 2 "Find the Following".. I need this by Thursday 4 PM, Dec 5.
Document Preview:
Hydration of NaOH: Mass of calorimeter = 5.86243g Mass of calorimeter + water = 53.5856g Mass of calorimeter + water + NaOH = 58.3960 g Mass of NaOH = 4.8104 g Mass of solution = 52.53357g Ti= 19.1o c ; Tf=46.235oc Find the followings: (show all steps) Heat absorbed by the solution (kJ) =? ?Hsoln (kj) =? Moles of NaOH =? Molar enthalpy of solution (kj.mol-1) =? Neutralization of NaOH: Concentration of HCl used = 0.2 M Volume of HCl used = 45 ml Ti of HCl/ NaOH before mixing = 18.9oC ; Tf= 31.736oC Mass of calorimeter + solution after cooling= 109.4387 g Mass of solution= 103.57627 Find the followings: (show all steps) Heat released by neutralization=? Moles of HCL=? Limiting reagent=? Molar enthalpy of neutralization (kJ.mol-1)
