The reaction of an acid such as HCl with a base, such as NaOH, in water is an exothermic reaction. HCl(aq) + NaOH(aq) ---> NaCl(aq) + H2O In one experiment, a student placed 55.0 mL of 1.00 M HCl in a coffee-cup calorimeter and carefully measured its temperature to be 35.5oC. To this was added 55.0 mL of 1.00 M NaOH solution whose temperature was also 35.5oC. The mixture was quickly stirred, and the student noticed that the temperature of...

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...

4. A styrofoam-cup calorimeter containing 150 g of water is calibrated by generating 1770 J of heat within it. The temperature increases by 1.67°C. What is the calorimeter constant Ccal (heat capacity of the calorimeter)? c(H20) = 4.184 Jg='K 5. A constant-pressure calorimeter, Where Ccal = 192 JK I. contains 100.0 mL of a 0.200 M aqueous solution of AgNO3. The temperature of the calorimeter and its contents is 22.30°C. Upon addition of 100.0 mL of 0.200 M solution of...

3) You would like to measure the heat of neutralization of an acid with a base. You mix 225 mL each of 0.65 M HNO, and 0.65 M LiOH, both at a temperature of 18.1 °C in a calorimeter cup equilibrated to that same temperature. After following the temperature change for 10 min and extrapolating it back to the time of addition, you find that the "final temperature" after mixing was 22.3 °C. Previously, you measured the heat capacity of...

1. 50 mL of water at 51.9°C were mixed with 50 mL of water at 23.2°C in a calorimeter also at 23.2°C. The final temperature was 33.1°C. Assuming that neither the density of water nor its specific heat capacity change with temperature, calculate the total heat capacity of the calorimeter. (density of water = 1.00 g mlº', specific heat capacity=4.18 J g?K=) 2. When 5.00 g of NaOH(s) are added to 100 g of water (using the same calorimeter as...

A common laboratory reaction is the neutralization of an acid with a base. When 49.6 mL of 0.500 M HCl at 25.0°C is added to 52.0 mL of 0.500 M NaOH at 25.0°C in a coffee cup calorimeter (with a negligible heat capacity), the temperature of the mixture rises to 28.2°C. What is the heat of reaction per mole of NaCl (in kJ/mol)? Assume the mixture has a specific heat capacity of 4.18 J/(g·K) and that the densities of the...
