Question:

(A) What mass of sucrose must be burned to produce 1.00 x 10³ kJ of heat?

(B) A 25.0 mL sample of 0.1045 M HCl(aq) was neutralized by NaOH(aq). Use the result of Example 7-4 to determine the heat evolved in this neutralization.

Example 7-4

In the neutralization of a strong acid with a strong base, the essential reaction is the combination of H⁺(aq) and OH^-(aq) to form water.

Two solutions, 25.00 mL of 2.50 M HCl(aq) and 25.00 mL of 2.50 M NaOH(aq), both initially at 21.1 °C, are added to a Styrofoam-cup calorimeter and allowed to react. The temperature rises to 37.8 °C. Determine the heat of the neutralization reaction, expressed per mole of H₂O formed. Is the reaction endothermic or exothermic?
