A 16.260g piece of metal was heated in a hot water bath at . The hot metal was then transferred to a calorimeter containing 50.00 mL of water (d of H2O= 1.00 g/mL). From the time-temperature plot, the initial and final temperature for the water were determined to be and , respectively. A) calculate heat (q) gained by the calorimeter and water assuming Ccal= , qH2O= (4.184 J/gC)(mwater)() and qcal=Ccal. 95.5°C 23.76°C 26.18°C 21.0J/ C T We were unable to...
Only question 4 Pliz!! ULT Appron male equul number of points de 3. A 32.520 g piece of unknown metal was heated in a hot water bath at 99.80°C. The hot metal was then transferred to a coffee-cup calorimeter containing 100.0 mL of water. Time-Temperature data was collected and plotted. From the plot, the initial and final tem- peratures for the water were determined to be T = 23.76°C and T, = 26.18°C. a. Calculate qcal and water (Assume Cal...

A student heats 84.17 mL of water to 95.27°C using a hot plate. The heated water is added to a calorimeter containing 73.92 mL of cold water. The water temperature in the calorimeter rises from J 2.15°C to 40.70°C. The specific heat capacity of water is 4.184 and the density of water is g. °C 1.00 mL Assuming that heat was transferred from the hot water to the cold water and the calorimeter, determine the heat capacity of the calorimeter....
