Average decomposition rate of the organic acid
A monoprotic organic acid decomposes after an enzyme is added to the solution. The initial concentration of the acid is 1.55 mol/L. After 354 sec, you take a 15.00 mL sample, titrate it with 0.120 mol/L NaOH solution, and reach the equivalence point after adding 52.36 mL. Compute the average decomposition rate of the organic acid.
determine K for this reaction When a sample of 5.63 grams of pure C 5 H 6 O 3 (g) was sealed into an otherwise empty flask of 2.50 L and heated to 200.
What is the geometry and hybridization of the carbonyl carbon in carboxylic acids and their derivatives.
The half-life of Plutonium-239 is 24,000 years. If 10 gms are present now, how long will it take until only 10% of the original sample remains? Round your answer to the nearest 10,000th.
Anton Von L. a 17th century pioneer in the use of the microscope, described the microrganisms he saw as "animalcules" whose length was "25 thousandths of an inch."
What is the volume of a gas at T=35.0C and P=675 torr if the same sample occupied 42.6L at T=-27.3C and P=1.000 atm.
Draw structural formulas for all of the structural isomers of C4H10, C5H12 and C3H7Cl.
A 2.30 L sample of O2(g) was collected over a liquid at a total pressure of 785 torr and 25°C. When the O2(g) was dried (vapor of that liquid removed), the gas had a volume of 1.86 L at 25°C and 785 torr.
