Question 1

An 8.21 g sample of glycerol (C3H8O3, molar mass = 92.0938 g mol-1) was combusted in a bomb calorimeter with a heat capacity of 10.61 kJ °C-1. If the temperature increased from 22.1 °C to 36.0 °C, determine DrU for the combustion of glycerol.
◦ -4.38 × 103 kJ mol-1
◦ -2.18 × 103 kJ mol-1
◦ 3.65 × 103 kJ mol-1
◦ 2.18 × 103 kJ mol-1
◦ -1.65 × 103 kJ mol-1

Question 2

Calculate the amount (mass) of acetic acid (C2H4O2, molar mass = 60.052 g mol-1) that causes a bomb calorimeter with a heat capacity of 8.43 kJ °C-1 to have a temperature increase from 24.5 °C to 36.8 °C. The DrU for the combustion of acetic acid is -874.2 kJ mol-1.
◦ 6.18 g
◦ 2.18 g
◦ 8.68 g
◦ 7.12 g
◦ 9.66 g

Lower drug doses for elderly patients should be used first, with titrations of the dose as tolerated to prevent unwanted drug-related pharmacodynamic effects.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.
