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

Did you know?

The liver is the only organ that has the ability to regenerate itself after certain types of damage. As much as 25% of the liver can be removed, and it will still regenerate back to its original shape and size. However, the liver cannot regenerate after severe damage caused by alcohol.

Did you know?

Excessive alcohol use costs the country approximately $235 billion every year.

Did you know?

The lipid bilayer is made of phospholipids. They are arranged in a double layer because one of their ends is attracted to water while the other is repelled by water.

Did you know?

Not getting enough sleep can greatly weaken the immune system. Lack of sleep makes you more likely to catch a cold, or more difficult to fight off an infection.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
