Question 1

Aluminum metal has a specific heat of 0.900 J/g·°C. Calculate the amount of heat required to raise the temperature of 10.5 moles of Al from 30.5 °C to 225°C.
◦ 1.84 kJ
◦ 2.41 kJ
◦ 65.1 kJ
◦ 49.6 kJ
◦ 57.3 kJ

Question 2

Aluminum oxide can be reduced to aluminum metal using carbon, the other reaction product being carbon monoxide.  Determine the enthalpy change when 12.5 g of aluminum is produced by this method. [ΔH°f(carbon monoxide) = –110.5 kJ/mol; ΔH°f(aluminum oxide) = –1669.8 kJ/mol]
◦ 310 kJ
◦ 361 kJ
◦ 697 kJ
◦ 725 kJ
◦ 1504 kJ

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
