Question 1

A 0.600 g sample containing Ag2O and inert material is heated, causing the silver oxide to decompose according to the following equation:

2Ag2O(s) → 4Ag(s) + O2(g)

If 13.8 mL of gas are collected over water at 27 °C and 1.001 bar external pressure, what is the percentage of silver oxide in the sample? The partial pressure of water is 26.7 mmHg at 27 °C.
◦ 10.4%
◦ 44.8%
◦ 20.9%
◦ 41.8%

Question 2

What is the average speed (actually the root mean square speed) of a neon atom at 27 °C?
◦ 5.78 m s-1
◦ 609 m s-1
◦ 183 m s-1
◦ 19.3 m s-1

Aspirin may benefit 11 different cancers, including those of the colon, pancreas, lungs, prostate, breasts, and leukemia.

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).

Did you know?

Asthma attacks and symptoms usually get started by specific triggers (such as viruses, allergies, gases, and air particles). You should talk to your doctor about these triggers and find ways to avoid or get rid of them.

Did you know?

The average human gut is home to perhaps 500 to 1,000 different species of bacteria.
