H2SO4 + 2 NaOH → Na2SO4 + 2 H2O
To calculate the heat produced by the reaction, use q = mC∆T
q = heat
m = mass of the solution = 25.0 ml + 50.0 ml = 75.0 ml x 1 g / ml = 75.0 g of solution
C = specific heat = 4.184 J/gº
∆T = change in temperature = 28.9º - 25.0º = 3.90º
q = (75.0 g)(4.184 J/gº)(3.9º)
q = 1223.8 J = 1220 J (3 sig. figs.)
Note: the balanced reaction and the concentrations of H2SO4 and NaOH don't come into play unless you wanted to find the ∆Hrxn of reaction on a per mole basis.
