1. Calculate the heat required to melt 5.4 g of naphthalene, C.H. AH, -18.8kJ /mol 2. Ice at -10.0° C is combined with 50.0g of water at 75.0°C. Calculate the grams of ice present initially if the entire mixture comes to a final temperature of 25.0°C after the ice melts. Specific heat of water is 4.18 J/gºC, AH, = 334J/g Specific heat of water is 4.18 J/gºC, AH, = 3341/8 2. Consider the phase diagram of compound Z below: a....

15. A coffee cup calorimeter contains 400.0 g of water and 25.0 g of ice at 0.0 °C. When a 35.00 g scoop of calcium chloride (also at 0.0 °C) is added to the ice water, the calcium chloride dis- solves as shown. The heat produced by this reaction is enough to melt all of the ice and warm up the resulting calcium chloride solution. What is the final temperature of this solution? Assume there is no heat lost to...

Practice With Calorimetry And Heat 1. 75.0 g of cast iron was heated to 100°C and then plunged into 100 g of water at 23.0°C. Calculate the final temperature. Cast iron has specific heat of 0.46 J/gºc 2. A 25.0 g sample of an unknown metal at 99.5°C is placed into a calorimeter holding 50.0 g of water at 22.3°C. The final temperature was 26.2°C; what was the specific heat of the metal? 3. 30.0 g of water at 7.00°C...

2. 44.0 g of ice at –20.0 °C is mixed with 325 g of water at 32.1 °C. Calculate the final temperature of the mixture. Assume that no energy in the form of heat is transferred to the environment. (Heat of fusion = 333 J/g; specific heat capacities: ice = 2.06 J/g-K, liquid water = 4.184 J/g-K) ***HINT: Remember that ice melts at 0 °C***

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...
