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

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

All adverse reactions are commonly charted in red ink in the patient's record and usually are noted on the front of the chart. Failure to follow correct documentation procedures may result in malpractice lawsuits.

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).
