Question

• 50.5 kJ of heat is released when 1 mole of HCl reacts with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H2O. Write a thermochemical equation for this reaction.

•The equation below shows that dissolving 1 mole of NaOH in water releases 40.05 kJ of heat (q). What if there was 2 moles of NaOH, how much heat would be released (q)?

NaOH(s) ​​​​Na+(aq)​+​OH-(aq)​​+​40.05 kJ

• From the equation above, calculate the amount of NaOH that needs to be dissolved (in moles) in order to release 1000 kJ of heat (q).

• What should happen to the temperature of the solution produced from dissolving NaOH(s) in distilled water?

• Write the following sentence as a chemical equation:

“When 1 mole of HCl(aq) neutralizes 1 mole of NaOH(aq), 100.1 kJ is released”
