Chemistry

Q2: When 500.0 mL of 2.00 M Ba(NO3)2 solution at 25.0 °C ismixed with 500.0 mL of 2.00 M Na2SO4 solution at 22.0°C in acoffee-cup calorimeter, the white solid BaSO4 forms, and thetemperature increases to 28.2°C. Assume that the calorimeter isinsulated and has negligible heat capacity, the specific heatcapacity of the solution is 4.184 J/g°C, and the density of thefinal solution is 1.0 g/mL. Answer the questions below using theBalanced Equation: Ba(NO3)2 (aq)+ Na2SO4 > BaSO4 (s) + 2NaNO3(aq). Answer to correct amount of Significant Figures
