H-Br 364
Calculate the number of moles of benzaldehyde and thiamine hydrochloride used in the Procedure. Explain why benzaldehyde is used for the theoretical yield calculation
To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass. Calculate how many pounds of strawberries are needed to make a..
shown to contain 12.518 g silver, 0.6970 g carbon, and 2.786 g oxygen. What is the empirical formula of the sample?
Dissolve a compound with a molecular mass of 272.05 in a 10-mL volumetric flask. You remove a 1.00-mL aliquot, place it in a 25-mL volumetric flask and dilute it to the mark.
When silver crystallizes, it forms face-centered cubic cells. The unit cell edge length is 408.7 pm. Calculate the density of silver. (Enter answer to three significant figures.)
calculate the molar mass of the acid. B. After 10.00 mL of base had been added during the titration, the pH was found to be 5.87. What is the Ka of the unknown acid
The rate law for the decomposition of ozone to molecular oxygen: 2O3(g) --> 3O2(g) and the mechanism proposed for this process is: O3 O + O2 and O + O3 --K2--> 2O2. Derive the rate law in terms of K1, K-1 and K2.
What is the change in entropy of a system consisting of one mole of ideal gas when it is expanded isothermally and reversibly from a pressure of 6 bar to 2 bar at 275 K? What is the change of entropy of the surroundings?
what is the purpose of the anhydrous cacl2? the important that none of the solid cacl2 be included in the final distillation of 1-bromobutane.
Benzene, C6H6, is reacted with bromine, Br2, to produce bromobenzene, C6H5Br, and hydrogen bromide, HBr, as shown below. When 40.0 g of benzene are reacted with 95.0 g of bromine, 65.0 g of bromobenzene is produced.
how many moles of C3H8 need to react to release 5280 kJ of energy?
In the mammalian system, typical fatty acid synthesized for energy and storage are generally have 16 carbons. However, the typical fatty acid found in breast milk is C12 to C14. Explain how the synthesis of fatty acids in the mammary glands differ..
