When 10.00 ml of 1.00 m hcl solution is mixed with 115 ml of 0.100 m naoh solution in a constant-pressure calorimeter, the temperature rises from 22.45 °c to 23.25 °

c. calculate q for this reaction, assuming that the heat capacity of the calorimeter is the same as that of 125 g of water.?

    We can use the formula

    q = m cp ΔT

    The

    cp of water is 4.18 J/g K

    q = 125 (4.18) (23.25 - 22.45)

    q = 418 J

    The heat evolved for the neutralization reaction is equal to 418 J.
