Salicylic Acid and Acetic Anhydride --> Acetylsalicylic Acid and Acetic Acid C7H6O3 + C4H6O3 --> C9H8O4 + C2H4O2 Salicylic Acid - 1.75g 1.6 equivalents of acetic anhydride for every equivalent of salicylic acid.
The experimentally measured density under the same conditions is 3.10 g/L. Account for the discrepancy between your calculated value and the experimental result.
Background: If aqueous NaOH is added to tert-butyl chloride acetone solution, initially the solution is basic due to the hydroxide ions from the NaOH.
For the reaction 2A + B --> 2C, if B is initially 4.0M and 2min later is 3.0M, what is the rate of appearance of C?
If a solution containing 54.368 mercury(II) perchlorate is allowed to react completely with a solution containing 15.488 g of sodium sulfate, how many grams of solid precipitate will be formed?
what is the final volume of a 400.0 ml gas sample that is subjected to a temperature change from 22.0 degrees C to 30.0 degrees C and a pressure change from 760 mm Hg to 360 mm Hg
What are your actual experimental ratios? Give possible reasons for any observed variations from these ratios.
magnesium ion solution and another electrode composed of silver in a 1.0 M silver ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25 °C. Standard reduction potentials
a TIre has a volume of 535 cm3 at a temprature of 20 c while in use the temprature of the tire rises to 65 c calculet the new volume of the tire assuming a constant pressure and amount of air?
Ozonolysis of A followed by dimethyl sulfide reduction produces a single optically active compound C, C5H8O2. Reduction of C with ethereal LiAlH4 affords optically active compound D (C5H12O2) of the (S)-configuration. The 13C NMR spectrum of D is ..
