Question:

(A) Two solutions, 100.0 mL of 1.00 M AgNO31aq2 and 100.0 mL of 1.00 M NaCl1aq2, both initially at 22.4 °C, are added to a Styrofoam-cup calorimeter and allowed to react. The temperature rises to 30.2 °C. Determine qrxn per mole of AgCl1s2 in the reaction.

Ag+ (aq) + CI (aq) AgCl(s)

(B) Two solutions, 100.0 mL of 1.020 M HCl and 50.0 mL of 1.988 M NaOH, both initially at 24.52 °C, are mixed in a Styrofoam-cup calorimeter. What will be the final temperature of the mixture? Make the same assumptions, and use the heat of neutralization established in Example 7-4.

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.

H(aq) + OH(aq) HO(1)

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?
