Label the carbons in pyruvate relative to the carbons from which they were derived in glucose for example carbon one from glucose is found at which location in pyruvate. Utilize the labeling system derived from organic chemistry where the carbonyl carbon would be one in all compounds with a carbonyl- use the carbon numbers from glucose.
A catalyst has a avoid fraction of 0.40, an internal surface area of 180 m2/g and a pellet density of 1.40 g/cm3. Estimate the effective diffusivity of thiophene with hydrogen

magnesium undergoes a single displacement raction with hydrochlic acid. how many grams of hydrogen gas will be produced from the reaction of 3.00 g of magnesium with 4.00 g of hydrochloric acid? identify the limiting and excess reactants.
Cv and Cp denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then (A) Cp âˆ' Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
A typical aspirin tablet contains 325 mg of acetylsalicylic acid ( HC9H7O4). Calculate the pH of a solution that is prepared by dissolving five aspirin tablet(s) in one cup (237 mL) of solution. Assume the aspirin tablets are pure acetylsalicylic ..
Calculate concentration of chromate ion (CrO4) in a 0450 M solution of chromic acid (H2CrO4). (for chromic acid, Ka = .18, Ka2 = 3.2 x 10E-7)
Compound A has a λmax at 232 nm in its UV spectrum but will not react with any dienophile in a Diels-Alder fashion. Provide a structure for Compound A, and explain how you arrived at your decision.
Since the blades of ice skates are very thin, the pressure exerted by a skater can be quite large. Referring to the phase diagrams for carbon dioxide and water, explain whether a rink can be constructed using dry ice (solid carbon dioxide).
