In the reaction between formic acid (HCHO2) and sodium hydroxide, water and sodium formate (NaCHO2) are formed. To determine the heat of reaction, 75 mL of 1.07 M HCHO2 was placed in a coffee cup calorimeter at a temperature of 20.6 °C, and 45 mL of 1.78 M NaOH, also at 20.6 °C, was added. The mixture was stirred quickly with a thermometer, and its temperature rose to 24.9 °C. Write the balanced chemical equation for the reaction. Calculate the heat of reaction in joules. Assume that the specific heats of all solutions are 4.184 J g-1°C-1 and that all densities are 1.00 g mL-1. What is the heat of reaction per mole of acid (in units of kJ mol-1). Write the balanced reaction that takes place:
