WebThe specific heat for water is 4.184 J/(g°C), however when solutes are dissolved in it the specific heat changes. For the NaOH and HCl reaction, the specific heat of the solution, c, is 4.025 J/(g°C) while for the Mg and MgO reactions with HCl, c is equal to 3.862 J/(g°C). Using these terms we obtain: - n o ΔHrxn = CcalΔT + (m)(c)(ΔT) where:
