Question

When 40.0 mL of 1.00 M H2SO4 is added to 80.0 mL of 1.00 M NaOH at 20.00°C in a coffee cup calorimeter, the temperature of the aqueous solution increases to 29.20°C. If the mass of the solution is 120.0 g and the specific heat of the calorimeter and solution is 4.184 J/g • °C, how much heat is given off in the reaction? (Ignore the mass of the calorimeter in the calculation.) Use mc019-1.jpg

Answer 2

We are requested to decide the warmth radiated in the response. Warmth emitted is resolved through the condition triangleH = mCp triangleT where m is the mass, Cp is the particular warmth and triangleT is the temperature contrast. Substituting, triangleH = 120 g (4.184 j/g •°c) (29.2°c). Heat given off is equal to 14.66 kJ or 14.7 rounded
