When 10.00 mL of a solution of strong acid is mixed with 100.00 mL of a solution of weak base in a coffee-cup calorimeter, the temperature rises from 22.6 oC to 27.6 oC. Determine q for the acid-base reaction, assuming that the liquids have densities of 1.00 g/mL and the same heat capacities as pure water.

A 189 mL solution of a dilute acid is added to 193 mL of a base solution in a coffee-cup calorimeter. The temperature of the solution increases from 22.31 oC to 25.32 oC. Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3) as water, calculate the heat (in J) transferred to the surroundings, qsurr.

In one of the General Chemistry experiments, you used a coffee-cup calorimeter to measure the heat of neutralization of selected acid-base reactions. The calorimeter consisted of two nested Styrofoam cups with a cardboard lid. A temperature probe was lowered in the solution through a hole in the lid. Is a coffee-cup calorimeter a constant-volume or a constant-pressure device? Is a coffee-cup calorimeter adiabatic? The coffee-cup calorimeter was calibrated by using the neutralization reaction between sodium hydroxide and hydrochloric acid. The...
