Calculate the approximate enthalpy of the reaction in joules.

Estimate that 1.0 mL of vinegar has the same thermal mass as 1.0 mL of water. Ignore the thermal mass of the sodium bicarbonate. Note: it takes about 4.2 joules (J) to change 1.0 gram (1.0 mL) of water 1.0 °C.

Volume of Vinegar 25 mL
Mass of Sodium Bicarbonate 1.3 g
Initial Temperature of Vinegar 22
