A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.1 °C. To this is added 50.0 mL of water that was originally a temperature of 54.9 °C. A careful plot of the recorded temperature established T0 as 31.3 °C. What is the calorimeter constant (J/°C)?

3. A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in the calorimeter is determined to be 22.1 "C. To this is added 50.0 mL of water that was originally at a temperature of 54.5 C. A careful plot of the temperatures recorded after this established the temperature at T, was 31.86 °C. What is the calorimeter constant in J/C for this calorimeter?...
3. A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in the calorimeter is determined to be 22.7 °C. To this is added 50.0 mL of water that was originally at a temperature of 54.5 C.

In a coffee cup calorimeter, 50.0 mL of 1.00 M NaOH and 50.0 mL of 1.00 M HCl are mixed. Both solutions were originally at 24.6°C. After the reaction, the final temperature is 31.3°C. Given that the density of the NaCl solution is 1.038 g/mL and he specific of NaCl solution is 3.87 J/g-°C, calculate the ΔHneut/mole for the reaction of HCl with NaOH. Assume that no heat is lost to the surroundings. Part A. ) Why are the density...

When 1.00 g of CaCl2 is added to 50.0 g of water in a coffee-cup calorimeter, it dissolves according to the following eqn: CaCl2 (s) Ca2 (aq) + 2Cl (aq) The temperature of the solution rises from 25.00°C to 28.51 °C. Assuming that all the heat flow involved in the reaction is transferred to the water, calculate q Also, assume that the csoln is equal to cwater Which is 4.18 J/g °C
Part A In the following experiment, a coffee-cup calorimeter containing 100 mL of H2O is used. The initial temperature of the calorimeter is 23.0 °C. If 3.10 g of CaCl2 is added to the calorimeter what will be the final temperature of the solution in the calorimeter?

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solutiorn phase reaction. Thermometer Stirring rod A student heats 63.92 grams of iron to 98.03 °C and then drops it into a cup containing 75.92 grams of water at 24.47 °C. She measures the final temperature to be 30.66 °C The heat capacity of the calorimeter (sometimes referred to as the...
