1) Carbon dioxide decomposes into CO and O2
at elevated temperatures. What is the equilibrium partial pressure of oxygen in a sample at 1000°C for which the initial pressure of CO2 was 1.15 atm?
2) How many molecules of oxygen are found in 3.00 moles of oxygen?
3) 2.3 moles of ammonia (NH3) is formed in the following reaction. How many grams of hydrogen reacted?
3H2 + N2 --> 2NH3
4) A beaker of a CH3COOH solution is found to have a pH of 2.3. What
is the concentration of CH3COOH in solution? (Ka for CH3COOH is 1.8 × 10−5)
