(a)
Interpretation:
Energy unit conversion should be done between cal and kcal.
Concept Introduction:
The Calorie and calorie are different from each other by their definition. Calorie is kilocalorie and the unit is represented as kcal or Cal. Similarly, calorie is represented as cal.
The following conversion factor can be used;

- For each of the following situations ac. use the following choices iiii to complete the statement “The final temperature of the water should be” ol type='a'> Between 50 °C and 90 °C 50°C Between 10 °C and 50 °C A 100.0-g sample of water at 90 °C is added to a 100.0-g sample of water at 10 °C. A 100.0-g sample of water at 90 °C is added to a 500.0-g sample of water at 10 °C. You have a Styrofoam cup with 50.0 g of water at 10 °C. You add a 50.0-g iron ball al 90 °C to the water.arrow_forwardInsoluble AgCl(s) precipitates when solutions of AgNO3(aq) and NaCl(aq) are mixed. AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) rH = ? To measure the energy evolved in this reaction, 250. mL of 0.16 M AgNO3(aq) and 125 mL of 0.32 M NaCl(aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises from 21.15 C to 22.90 C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol. (Assume the density of the solution is 1.0 g/mL and its specific heat capacity is 4.2 J/g K.)arrow_forwardCopper is used in building the integrated circuits, chips, and printed circuit boards for computers. When 228 J of heat are absorbed by 125 g of copper at 22.38C, the temperature rises to 27.12C. What is the specific heat of copper?arrow_forward
