Assuming that the gas is ideal, calculate the work required to compress Ar gas from 10L to 1L. The gas is initially at 25 degrees Celsius and 1 bar.
Aspirin is a weak monoprotic acid with a ka of 3.27 X 104. Assume you dissolve 0.650 g of aspirin in 200 mL of water as well as titrated it with 0.100 M NaOH.
For a given transfer of energy, a greater change in disorder occurs when the temperature is high.
When iron chloride FeCl3 is dissolved in water the solution becomes acidic. The preparation of the Fe(NO3)3 solution and the KSCN solution used 0.5 M HNO3 as the solvent instead of water. Explain why this was done. Hint: Consider Le Chatelier's Pr..
