3 NaOH(aq) + H3PO4(aq) → Na3P03(aq)+ 3 H20(1) AH = -173.7 kJ If 31.2 mL of 0.45 M sodium hydroxide is mixed with 65.4 mL|of 0.088 M phosphoric acid, how many kJ of heat are produced? Show your work. When the above solutions are mixed, what final temperature should we expect the solution to reach? Assume the combined solution has the same density (1 g/mL) and heat capacity (4.184 J/g.°C) as water and that it is initially at 22.4 °C. Show your work.
