A) Draw the major organic product obtained when 1,2-dimethylcyclohexane-1,2-diol encounters periodic acid.
B) draw the skeletal structure of the oxidation product: ethanol + Cr+6 ----H+----> Cr+4 + oxidation product.
Colbalt monoxide CoO, the blue color in ceramics glazes, is prepared by decomposing cobalt (II,III) oxide at 950degree celsius.
we then titrated both the aqueous and organic layer. for organic layer, we used 0.1M (S2O3)2- for aqueous layer, we used 0.01M (S203)2- find concentration [I]2 (subscript 2) for aqueous and organic layer
Calculate percent recovery of panacetin from the individual masses of its mictures, sucrose (.044g), aspirine (.093), and the unknown (.339).
What pressure would have to be applied to a 28.0mL sample of gas at 25°C and 1.00atm to compress its volume to 10.0mL at constant temperature?
A gas mixture contains 1.30g N2 and 0.95g O2 in a 1.57-L container at 22 degrees Celsius. Calculate the mole fraction of N2.
In chemical reactions the total number of moles of products must be the same as the total number of moles of reactants.
At what temperature would a 1.80 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 degrees C/m. answer in degrees C
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
Aqueous hydrobromic acid will react with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . Suppose 36.4 g of hydrobromic acid is mixed with 5.9 g of sodium hydroxide.
CH3OH burns in oxygen (O2) to from carbon dioxide (CO2) and water(H2O). Equal masses of ten grams of gaseous CH3OH and O2 are placed in an evacuated flask of five litres at the temperature of 25 degrees celsius.
A sample containing 2.20 moles of neon gas has a volume of 8.00 L. Assume that the pressure and the temperature remain constant. What is the new volume of gas in liters when a sample of 70.0 g neon is added to the neon gas already in the container..
calcutate the molecular weight of surfur if 35.5 grams of sulfur dissolve in 100 grams of CS2 to produce a solution that has a boiling point of 49.48c.
