The composition of a gas on a dry basis is 71.0 mole% N2, 12.0% O2, 12.0% CO2, and 5.0% CO. If the mole fraction of water is 0.160, what is the gas composition on a wet basis?
A solution is made by adding 0.51 mol of lithium hydroxide (LiOH) in enough water to form 5 L of solution. Calculate the pH.
What information is obtained from analyzing the blank? Is this sample 100% elution solvent?
Explain why dichloroethene has a boiling point of 60 degrees C while trans-dichloroethene as a boiling point of 48 degrees C. Include drawings of the structures with dipoles in your answer.
What product would you expect to make? Propose a detailed reaction mechanism for this reaction. What by-products might be expected in this experiment?
each square foot of lawn accumulates 1150 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? Assume an average snow flake has a mass of 1.80 mg.
A gas is allowed to expand at constant temperature from a volume of 2.0L to 11.2 L against an external pressure of 0.750 atm. If the gas absorbs 128 J of heat from the surroundings
The boiling point of another member of this homologous series was found to be 309 rm K. What is the likely molecular formula for this compound?
What is the ratio of the enantiomeric products? b) What name is given to a mixture of enantiomers present in the ratio determined in part (a)?
Why do we use an ethyl acetate/hexane mixture as a solvent in reaction of cyclopentadiene with maleic anhydride, rather than just pure hexane or ethyl acetate?
Explain why does ATP synthesis occur in the presence of Rotenone ( an inhibitor of one the reactions in the electron transport system.) if succinate is combined but not ATP synthesis doesn't occur if L-malate is added?
When you have two primary or two secondary alcohols on the same molecule, will both undergo oxidation or just one?
