In a coffee-cup calorimeter, 50.0mL of 0.100M AgNO3 and 50.0mL of 0.100M HCl are mixed to yield the following reaction:Ag + (aq) + Cl - (aq) - --> AgCl (s) The 2 solutions were initially at 22.60 degree C, and the final temperature is 23.40 degree C. Assuming that the combined solution has a mass of 100.0g and a specific heat capacity of 4.18 J/Cg, the heat loss (q) that accompanies this reaction is ___J.

334.4J

Explanation:

Q = mass*specific heat capacity (final temperature - initial temperature) = 100 * 4.18 (23.40 - 22.60) = 100 * 4.18 * 0.80 = 334.4J
