1st attempt See Periodic Table See Hint COAST Tutorial Problem Phthalates used as plasticizers in rubber and plastic products are believed to act as hormone mimics in humans. The value of AH comb for dimethylphthalate (C10H1004) is -4685 kJ/mol. Assume 0.870 g of dimethylphthalate is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 6.35 kJ/°C at 21.5°C. What is the final temperature of the calorimeter? "С SUBMIT ANSWER 1 OF 5 QUESTIONS COMPLETED < 04/05 >
The flavor of anise is due to anethole, a compound with the molecular formula C10H12O. The ΔHcomb value for anethole is -5539 kJ/mol. Assume 0.755 g of anethole is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 6.50 kJ/°C at 20.6 °C. What is the final temperature of the calorimeter?
Styrene, CgHg, is one of the substances used in the production of synthetic rubber. When styrene burns in oxygen to form carbon dioxide and liquid water under standard-state conditions at 25°C, 42.15 kJ are released per gram of styrene. Find the standard enthalpy of formation of styrene at 25°C, AH" (C02(9)) = -393.5 kJ/mol, AH®:(H,0(I) = -285.8 kJ/mol Select one: a. - 4390 kJ/mol b.-1044 kJ/mol c. -8681 kJ/mol d. +99 kJ/mol O e. +637 kJ/mol The heat of solution...
