State the mechanism, showing electron flow with arrows for the acid-catalyzed hydrolysis of methyl benzoate to benzoic acid as well as methanol-the reverse of Fischer esterification.
The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hyrdrogen, and oxygen. A 2.626 g sample of BHT was combusted in an oxygen rich environment to produce 7.867g of
The atmosphere becomes colder at higher elevation. As an average the standard atmospheric absolute temperature can be expressed as Tatm = 288 - 6.5 × 10?3 z, where z is the elevation in meters.
what is the [OH-] in a solution that has a pOH of 2.70? Use E notation with 3 significant figures.
what is the density of hydrogen sulfide at 1.2 atm and 307 K? answer in units of g/L
to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
The product of this reaction contains two stereocenters. Due to the stereospecificity of the bromination and the symmetry of the product, however, only the meso-diastereomer of stilbene dibromide is produced.
When the sodium atom becomes a sodium ion, how does the size and electron configuration of the sodium atom change?
Write the mechanism showing electron flow with arrows, for the acid-catalyzed hydrolysis of methyl benzoate
effuse through a membrane. How long would it take the same number of moles of Ar(g) to effuse through the same membrane?
1.925 g of methanol is burned in a bond calorimeter with a heat capacity of 10.4 kj/c .how much heat is given off in kj/g if the temperature increase 4.19 c
