A mixture of CO(g) and O2 (g) in a 1.0-L container at 1.0x10^3 Kelvin has a total pressure of 2.2 atm. After some time the total pressure falls to 1.9 atm as the result of formation of CO2. Find the mass (in grams) of CO2 that forms.
What is the amount of volume of the solvent you need to extract 65g of the solute in one extraction from the original 100g dissolved in 206mL water?
Estimate how many barrels of fluid this tank could hold. Clearly state any assumption you must make to determine this and explain how you arrived at your assumption
If 120.9 mL of water is shaken with a gas at 0.860 atm, it will dissolve 0.00286 g of the gas. Estimate the Henry's law constant for the gas in water in units of g L-1 atm-1.
What makes Maleic acid (isomer of but-2-enedoic acid), very soluble in water and only sparingly soluble in CCl4
Why is it preferable to use a metal ion buffer to achieve pM = 7, rather than just dissolving enough M to give a 10-7 M solution?
Explain, using resonance as part of your answer, why a hydrogen adjacent to carbonyl groups (a-H's) are acidic. b. Give the mechanism for the Claisen ester condensation reaction.
Calculate the final temperature of a mixture of 170.0 g of ice initially at -16.5 degrees celsius and 334.5 g of water initially
Lindane is a popular pesticide throughout the south because it is a persistent chemical (i.e. it remains in the environment and offers protection for a long period of time)
A helium-filled balloon has a volume of 2.75 L at 17 C. The volume of the balloon decreases to 2.36 L after it is placed outside on a cold day. What is the outside temperature in K?
Draw a flame ionization detector FID using the following parts: column, flame, hydrogen, air, electrode, current meter
How many moles of S8 are needed to make 0.600 moles of SF4? S8 + 8 Cl2 = 8 SCl2 ; 3 SCl2 + 4 NaF = SF4 + S2Cl2 + 4 NaCl
