In Part B of the experiment, a student mixes 28.0 mL of 1.1 M with 28.0 mL of 1.000 M in a well‑insultated calorimeter and observes that the temperature of the solution increases by 6.16 C. These are similar conditions as the previous two problems. How many moles of water are formed?
A student mixes 75.0 mL of water with 0.750 mol HCl at 25.0°C with 75.0 mL of water with 0.750 mol NaOH at 25.0°C in a foam cup calorimeter. The temperature of the resulting solution increases to 35°C. How much heat, in kJ, was released by the reaction. The specific heat of water is 4.18 J/g*°C. (Since the HCL and NaOH solutions are very dilute, you can assume that these solutions have the same specific heat as water. Recall, for...
