hello
please i want the asnwer with steps as soon as possible
thank you
The reaction 2NaOH(aq) + H2SO4(aq) Na2SO4(aq) + 2H2O() was studied in a coffee cup calorimeter. 100.0 mL portions of 1.00 M aqueous NaOH and H2S04 each at 24.0°C, were mixed. The maximum temperature achieved was 30.6°C. Neglect the heat capacity of the cup and the thermometer, and assume that the solution of products has a density of exactly 1.00 g/mL and a specific heat capacity of 4.18 J/(g K). No Standard Scientific Notation (No exponential). No Coma. No decimal Calculate the heat of reaction, q, in JExplanation / Answer
Qsolution = m*C*(Tf-Ti)
Qsoln = (100+100)(4.18)(330.6-24) = 256317.6 J
Qreaction = -Qsoln = -256317.6 J
now
moles = MV = 0.1*100 = 10 mmol
HRxn = -Qrxn / mmol = -256317.6/10
HRxn = -25631.76 J/mmol
HRxn = -25631.76 kJ/mol
