During an experiment, a student adds 1.23 g of CaO to 200.0 mL of 0.500 M HCl. The student observes a temperature increase of 5.10 °C. Assuming the solution\'s final volume is 200.0 mL, the density if 1.00 g/mL, and the heat capacity is 4.184 J/(g·°C), calculate the heat of the reaction, ΔHrxn.

    q = mass H2O x specific heat H2O x delta T.

  • Chemsitry -

    i know i need to use the equations q=mcdeltaT
    and delta H= q/n but i keep getting the wrong answer. also which one is the limiting reactant...
