You mix 2.58 grams of NaHCO3 with 49.00 grams of 1.00M HCl. The two react to form aqueous NaCl, water, and carbon dioxide. The initial temperature was 21.4°C and temperature at the end of the reaction was 17.4°C. Assume that the density of HCl is 1.00g/mL.
a. Write the balanced reaction.
b. The final temperature of the resulting solution was lower than the initial temperature. How did the energy flow?
The energy was released by the solution and absorbed by the reaction.
The energy was absorbed by the solution and released by the reaction.
C. Use the equation q = nCΔT to calculate the heat (kJ) involved in the reaction.
D. Calculate the number of moles of sodium bicarbonate and hydrochloric acid used in the reaction.
