In a coffee-cup calorimeter, 140.0 mL of 1.2 M NaOH and 140.0 mL of 1.2 M HCI are mixed. Both solutions were originally at 22.1°C. After the reaction, the final temperature

is 30.1°C. Assuming that all the solutions have a density of 1.0 g/cm³ and a specific heat capacity of 4.18 J/°C-g, calculate the enthalpy change for the neutralization of HCl by NaOH. Assume that no heat is lost to the surroundings or to the calorimeter. ΔΗ = kJ/mol Submit Answer Try Another Version 5 item attempts remaining
