(a) Draw the skeletal structure of the major organic product produced when 2-methylpropanoyl chloride reacts with 3-methylbutanoic acid in the presence of the weak base, pyridine.
What mass of AgBr would precipitate from this mixture? (Ksp of AgBr is 5.4x10^-13 & Kf of Ag(CN)2^1- is 1.0x10^21)
Using the average bond dissociation enthalpies(BE) given, estimate the standard molar heat of reaction of the gas-phase reaction of hydrogen peroxide with methanol to yield formaldehyde and water:
The product formed by the reaction of 3-methyl-1-butene with mercuric sulfate and sulfuric acid is?
The first equivalence point for the titration of 0.2567 grams of a weak acid is reached when a volume of 26.80mL of 0.0510 M NaOH(aq) has been added. What is the molar mass of the acid?
One of the lines of the hydrogen line spectrum has a wavelength of 434.1 nm. It is known that all of the visible lines of the hydrogen spectra result from an electron
