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
