Diisopropyl ether reacts with concentrated aqueous HI to form two initial organic products (A and B). Further reaction with HI produces organic product C from product B
hydrogen gas was collected over water in a eudiometer at 26 degrees c when the atmospheric pressure was 726 mm hg. What was the pressure of the hydrogen gas?
As the liquid vaporizes the plunger is pushed out. At equilibrium, the plunger reads 5.46 mL of gas. Atmospheric pressure is 740. mmHg. What is the approximate molar mass of the compound (in g/mol)?
The first mechanism includes sodium acetate to yield beta-penta-acetate and the first mechanism includes zinc chloride (Lewis acid) to form an oxonium ion to yield the alpha-penta-acetate product. Any help to draw out the mechs would be much appre..
Sulfurous acid, H2SO3, is a weak diprotic acid (pKa,1=1.89 and pKa,2=7.21 at 25oC). What is the pH of 0.121 mol/L H2SO3(aq) at 25oC? Give your answer accurate to two decimal places.
Four (4.00) moles of a perfect gas at 250.0 K and 1.50 bar pressure undergo a reversible isothermal compression until the pressure becomes 3.00 bar.
