In а cоffee cup cаlоrimeter, 50.0 mL оf 1.0 M NаOH and 50.0 mL of 1.0 M HCl are mixed. Both solutions are originally at 23.5o C and after the reaction, the final temperature is 29.9o Celsius. Calculate the enthalpy change for the neutralization of HCl by NaOH. Assume the densities and specific heat are those of water. Q = m x Cs x DT Specific heat of water: 4.184 J/g.oC
